ഇന്ത്യയിലെ ഏറ്റവും ആദരണീയനായ ശാസ്ത്രജ്ഞരിൽ ഒരാളും നോബൽ സമ്മാന ജേതാവുമായ സി വി രാമൻ എന്ന് അറിയപ്പെടുന്ന, സർ ചന്ദ്രശേഖര വെങ്കട രാമന്റെ ജന്മദിനമാണ് നവംബർ 7. 1888 നവംബർ 7 നായിരുന്നു അദ്ദേഹത്തിന്റെ ജനനം. 1970 ൽ അന്തരിച്ചു. ഒരു കോളജ് ലക്ചർ ആയിരുന്നു അദ്ദേഹത്തിന്റെ പിതാവ്.  ഗണിതശാസ്ത്രവും ഭൗതികശാസ്ത്രവും ആയിരുന്നു പിതാവ് കോളജിൽ പഠിപ്പിച്ചിരുന്നത്.  ഇതാണ് സിവിയേയും ശാസ്ത്ര വിഷയത്തിലേക്ക് അടുപ്പിച്ചത്. സി വി രാമനെക്കുറിച്ച് ചില കാര്യങ്ങൾ മനസിലാക്കാം

പാലിത് പ്രഫസർ ഓഫ് ഫിസിക്സ് 

1917 ൽ കൊൽക്കത്ത സർവകലാശാലയിൽ  സർ തരക നാഥ് പാലിതിന്റെ പേരിലുള്ള പാലിത് ചെയർ ഓ‌ഫ് ഫിസിക്സിൽ ആദ്യത്തെ ഭൗതിക ശാസ്ത്ര പ്രൊഫസറായി അദ്ദേഹം നിയമിതനായി. അതുകൊണ്ട് തന്നെ പാലിത് പ്രഫസർ ഓഫ് ഫിസിക്സ് എന്നായിരു‌ന്നു ഈ പദവി അറിയപ്പെട്ടിരുന്നത്.

കൊൽക്കത്ത സർവകലാശാലയിൽ അദ്ധ്യാപനം നടത്തുമ്പോൾ തന്നെ അദ്ദേഹം കൊൽക്കത്തയിലെ ഇന്ത്യൻ അസോസിയേഷൻ ഫോർ കൾട്ടിവേഷൻ ഓഫ് സയൻസിൽ (ഐ എ സി എസ്) ഗവേഷണം തുടർന്നു. പിന്നീട് അസോസിയേഷനിൽ ഓണററി സ്കോളറായി

ദേശീയ ശാസ്ത്ര ദിനം

നോബൽ സമ്മാനത്തിന് അർഹനാക്കിയ കണ്ടുപിടുത്തത്തിന് വഴിക്കാട്ടിയായ സുപ്രധാന പരീക്ഷണങ്ങൾ രാമൻ നടത്തിയത് ഐ എ സി എസിൽ വച്ചായിരുന്നു. പ്രകാശകിരണങ്ങളുടെ വിസരണം സംബന്ധിച്ച തന്റെ സുപ്രധാന കണ്ടെത്തൽ സി വി രാ‌മൻ നടത്തിയത് ഇവിടെ വച്ചായിരുന്നു. 1928 ഫെബ്രുവരി 18നായിരുന്നു അത്. ആ ദിവസമാണ് നമ്മൾ ദേശീയ ശാസ്ത്ര ദിവസമായി ആചരിക്കുന്നത്.

കെ എസ് കൃഷ്ണൻ

ഈ പരീക്ഷണത്തിൽ രാമനെ സഹായി‌ക്കാൻ ഒരു സഹായി ഉണ്ടായിരുന്ന കാര്യം പലർക്കും അറിയില്ല. രാമന്റെ സഹ‌പ്രവർത്തകനായ കെ എസ് കൃഷ്ണൻ ആയിരുന്നു അത്. നോബൽ സമ്മാനം വാങ്ങിക്കൊണ്ടുള്ള പ്രസംഗത്തിൽ കെ എസ് കൃഷ്ണന്റെ പേര് പരാമർശിക്കാൻ പക്ഷെ സി വി രാമൻ മറന്നിരുന്നില്ല.

റോയൽ സൊസൈറ്റിയിൽ അഗത്വം

ആറ്റോമിക് ന്യൂക്ലിയസും പ്രോട്ടോണും കണ്ടെത്തിയ ഡോ. ഏണസ്റ്റ് റുഥർഫോർഡ് 1929 ൽ ഇംഗ്ലണ്ടിലെ റോയൽ സൊസൈറ്റിയെ അഭിസംബോധന ചെയ്തുകൊണ്ട് നടത്തിയ പ്രസംഗത്തിൽ  രാമന്റെ സ്പെക്ട്രോസ്കോപ്പിയേക്കുറിച്ച് പരാമർശം നടത്തിയിരുന്നു. തുടർന്ന്  അദ്ദേഹത്തിന് റോയൽ സൊസൈറ്റിയിൽ അംഗത്വവും ലഭിച്ചു

നോബൽ സമ്മാനം

1928 മുതൽ സി വി രാമ‌ന് നോബൽ സമ്മാനത്തേക്കുറിച്ച് പ്രതീക്ഷയുണ്ടായിരുന്നു. രണ്ട് വർഷത്തിന് ശേഷം രാമൻ പ്രഭാവം എന്ന കണ്ടുപിടുത്തത്തിന് അദ്ദേഹത്തിന് നോബൽ സമ്മാനം ലഭിച്ചു. നവംബറിൽ നോബൽ സമ്മാനം വാങ്ങാനായി ജൂലൈയിൽ തന്നെ അദ്ദേഹം സ്വീഡ‌നിലേക്കുള്ള ടിക്കറ്റ് ബുക്ക് ചെയ്തിരുന്നു.

ആദ്യ ഏഷ്യക്കാരൻ

ശാസ്ത്രത്തിനുള്ള നോബൽ സമ്മാനം നേടിയ ആദ്യത്തെ ഏഷ്യക്കാരൻ മാത്രമല്ല, വെള്ളക്കാരനല്ലാത്ത ആദ്യ വ്യക്തികൂടിയാണ് സി വി രാമൻ.

ക്വാണ്ടം ഫോട്ടോൺ സ്പിൻ

1932 ൽ രാമനും സൂരി ഭാഗവന്തവും ക്വാണ്ടം ഫോട്ടോൺ സ്പിൻ കണ്ടെത്തി. ഈ കണ്ടെത്തൽ പ്രകാശത്തിന്റെ ക്വാണ്ടം സ്വഭാവം തെളിയിക്കാൻ കൂടുതൽ സഹായകരമായി.

കടലിന്റെ നീലിമ

1921 ൽ യൂറോപ്പിലേക്ക് പോകുമ്പോൾ അദ്ദേഹം കണ്ട, മെഡിറ്ററേനിയൻ കടലിന്റെ അത്ഭുതകരമായ നീല നിറമായിരുന്നു അദ്ദേഹം കണ്ടെത്തിയ ഒപ്‌റ്റിക്കൽ തിയറിക്ക് പ്രചോദനമായതെന്ന് അദ്ദേഹം പറഞ്ഞിരുന്നു 

പ്രകാശത്തിനൊപ്പം ശബ്ദവും

പ്രകാശത്തെക്കുറി‌ച്ചുള്ള പഠനത്തിൽ മാത്രമല്ല രാമൻ ശ്രദ്ധ പതിപ്പിച്ചത്. ശബ്ദശാസ്ത്രത്തിലും അദ്ദേഹം പരീക്ഷണം നടത്തി. ഇന്ത്യൻ ഡ്രമ്മുകളായ തബല, മൃതംഗം എന്നിവയുടെ ശബ്ദത്തിന്റെ സ്വരചേർച്ചയേക്കുറിച്ച് പഠനം നടത്തിയ ആദ്യത്തെ വ്യക്തികൂടിയാണ് സി വി രാമൻ

തപാൽ സ്റ്റാമ്പ്

1954 ൽ ഭാരത് രത്‌ന സമ്മാനി‌ച്ചാണ് അദ്ദേഹത്തെ രാജ്യം ആദരിച്ചത്. അദ്ദേഹത്തിന്റെ ആദ്യ മരണ വാർഷികത്തിൽ ഇന്ത്യൻ തപാൽ വകുപ്പ് സർ സി ​​വി രാമന്റെ സ്മരണയ്ക്കായ് സ്റ്റാമ്പ് പുറത്തിറക്കിയിരുന്നു

Raman completed his master’s in physics from the University of Madras in 1907 . Afterward, he took a job as an accountant with the Indian government but later became a physics professor at the University of Calcutta in 1917 .

While studying light’s behavior in different materials in 1928, he noticed a unique light scattering pattern. This discovery, known as the Raman frequencies, relates to energy changes in the substance the light passes through.

In 1929, Sir C.V. Raman was given the title of ‘knight’ . In 1933, he joined the Indian Institute of Science in Bangalore as the physics department head. By 1947, he led the Raman Research Institute. In 1961, he became part of the Pontifical Academy of Science.

He helped establish many Indian research centers, started the Indian Journal of Physics and the Indian Academy of Sciences, and trained many students. These students got significant roles in Indian and Myanmar universities and government. His nephew, Subrahmanyan Chandrasekhar, won the 1983 Nobel Prize for Physics alongside William Fowler.

C.V. Raman College

Sir C.V. Raman’s educational journey was marked by his time at the Presidency College in Madras (now Chennai) where he pursued his undergraduate and postgraduate studies in Physics.

What is C.V. Raman Effect?

The Raman effect describes how light changes its wavelength after interacting with molecules. When light passes through a clear, dust-free chemical sample, a tiny portion reflects in different directions from the original beam. Most reflected light has the same wavelength, but some don’t due to the Raman effect.

This phenomenon was named after Indian physicist Sir Chandrasekhara Venkata Raman, who reported it in 1928. Though the effect was described theoretically by Austrian physicist Adolf Smekal in 1923 and noticed by Russian physicists Leonid Mandelstam and Grigory Landsberg just a week before Raman, it’s Raman who gets the credit.

If we think of incoming light as made of particles or photons, these particles hit the sample’s molecules. Most times, they bounce back without changing. But sometimes, the molecules either take or give energy to these photons. This changes the photon’s energy, and hence its frequency. The change in frequency helps understand the energy shifts during this interaction.

However, the Raman effect is weak. In liquids, the changed light’s strength might be only a tiny fraction of the original beam. Still, the Raman pattern is unique for different molecules and shows how many molecules are involved. That’s why it’s useful in analyzing materials.

The energy changes in the Raman effect come from the molecule’s rotational and vibrational movements. It’s challenging to see just rotational changes, especially in liquids. Most studies focus on vibrational changes which are clearer and can be seen in gases, liquids, and solids. Among these, liquids and solids are studied more since gases show a very faint Raman effect.

C.V. Raman Contribution to Science

Sir C.V. Raman made good use of his time with Professor Jones during his physics studies at Presidency College. They had limited lab tools, but Raman used them to explore countless questions. Often, these questions had no answers in books, so Raman’s nature pushed him to do experiments.

He explored how light spreads even though he knew its wave nature. He showed his findings to Professor Jones, who took a long time to respond. Raman knew of a magazine, the Philosophical Magazine, maybe from a nearby library. In 1906, when he was only 18, he wrote a paper for it.

This was notable because his college wasn’t known for research. Soon after, R.W. Wood from Johns Hopkins University published a related paper and later announced Raman’s discovery of the Raman Effect.

In 1917, Raman moved to teach physics at the University of Calcutta and also worked at the IACS, climbing to a top position. He called this time his “golden age” and was surrounded by talented students. In 1929, he led an important science meeting.

C.V. Raman also studied the science behind musical instruments. He came up with ideas explaining how string instruments work, which was better than previous theories. He was the first to study sounds from Indian drums. In 1933, Raman became the director of the Indian Institute of Science in Bangalore.

Before him, most leaders and teachers there were British. He continued to teach physics for two more years. In 1947, when India became independent, he became its first National Professor. In 1948, he left the institute and in 1949 started the Raman Research in Bangalore, where he worked until he passed away in 1970.

C.V. Raman Achievements and Awards

Sir C.V. Raman received many honorary doctorates and was part of numerous science societies worldwide. He was part of societies in Munich, Zürich, Glasgow, Ireland, Hungary, the Soviet Union, America, Romania, and Czechoslovakia. In 1924, he became a Fellow of the Royal Society, but left in 1968, a unique case for an Indian. He led the 16th Indian Science Congress in 1929 and was the first leader of the Indian Academy of Sciences from 1933 until he passed away. In 1961, he joined the Pontifical Academy of Sciences.

Sir C.V. Raman worked for the Indian Finance Service and earned several awards. In 1912, he got the Curzon Research Award, and in 1913, the Woodburn Research Medal. In 1928, the Accademia Nazionale delle Scienze in Rome gave him the Matteucci Medal. He became a knight in 1930 and the Viceroy of India, Lord Irwin, honored him at the Viceroy’s House in New Delhi. He won the Nobel Prize in Physics in 1930 for his work on light scattering.

This made him the first Asian to win a Nobel Prize in Science. Rabindranath Tagore, another Indian, had won a Nobel Prize for Literature in 1913. Raman also received the Hughes Medal in 1930, the Franklin Medal in 1941, the Bharat Ratna award in 1954 (shared with C. Rajagopalachari and Sir Sarvepalli Radhakrishnan), and the Lenin Peace Prize in 1957.

CV Raman Essay

CV Raman represented and contributed significantly to India's scientific community as he was well-versed in philosophical thought and had an exquisite attention to detail. His discovery of the Raman Effect changed the world of science and made him the first ever Indian to be awarded the Nobel Prize in Physics in 1930. Here are a few sample essays on ‘ CV Raman ’.

200 words on essay on cv raman, 500 words on essay on cv raman.

Since his father taught physics and mathematics at AV Narasimha Rao College in Visakhapatnam, CV Raman was raised in an academic environment. Raman was a dedicated student. He enrolled in the Presidency College in Madras in 1902, and in 1904 he successfully completed his BA programme, earning first place and a gold medal in Physics. He received the highest honours when he earned his MA in 1907. His early studies in optics and acoustics—the two areas of study to which he devoted his whole professional life—were conducted while he was still a student. Raman's primary study was on musical instruments and acoustics, which helped him be elected as a fellow of the Royal Society in 1924.

Early Life | C. V. Raman was born in Madras Province, India on November 7, 1888 in Thiruvanaikoil, Tiruchirappalli. His full name was Chandrasekhara Venkata Raman. He was the son of Parvati Ammal and R. Chandrasekhara Ver. His father taught physics and mathematics at Presidency College in Madras. His early studies in optics and acoustics were conducted while he was still a student. Raman began working for the Indian Finance Department in 1907 after finding that a scientific career did not appear to give the best opportunities at the time. Raman found opportunities to do experimental research in the lab of the Indian Association for the Cultivation of Sciences in Calcutta, despite his office duties consuming the majority of his time.

Accomplishments | The advancement of science in India was influenced by the work of Indian physicist C. V. Raman. In 1930, he became the first Indian scientist to receive the prestigious Nobel Prize in Physics. His discovery is commonly referred to as the "Raman effect" or "Raman scattering," which is the inelastic scattering of a photon. He received numerous honorary doctorates and memberships in prestigious scientific institutions. He passed away in Bangalore on November 21, 1970, at the age of 82. In India, National Science Day is observed on February 28 every year to commemorate the day that Indian scientist Sir Chandrasekhara Venkata Raman discovered the Raman phenomenon.

CV Raman was the first Indian and Asian to be awarded the Physics Nobel Prize. Most importantly, he accomplished this while India was not well-known in the scientific community.

The Raman Effect

In 1928, while researching how light refracts in different materials, he discovered that when a transparent substance is lit by a beam of light of a particular frequency, a small amount of the light exits at right angles to the original direction, some of which is of a different frequency from the incident light. The energies connected to changes in rotational and vibrational states in the scattering material were named as Raman frequencies. In short, the Raman effect, discovered by C.V. Raman, occurs when light that shines through a material is scattered and its wavelength varies from that of the original incident light due to interactions with the molecules in the substance.

Academic Contribution

Raman received his knighthood in 1929, and in 1933 he relocated to the Indian Institute of Science in Bangalore to take over the physics department. He was appointed the Raman Research Institute's director there in 1947, and in 1961 he was elected a member of the Pontifical Academy of Science. He helped establish almost all Indian research institutions during his lifetime, founded the Indian Journal of Physics and the Indian Academy of Sciences, and mentored hundreds of students who went on to hold significant positions in academic institutions and government in India and Myanmar (Burma).

His Work and Achievements

After spending 15 years in Calcutta, he moved to Bangalore to work as a professor at the Indian Institute of Science (1933–1948), and in 1948 he was appointed director of the Raman Institute of Research, which he had founded and endowed. The Indian Association for the Cultivation of Sciences appointed him as Honorary Secretary. In 1926, he also started the Indian Journal of Physics, serving as its Editor. Raman supported the creation of the Indian Academy of Sciences and presided over it. He also served as the president of the Bangalore Current Science Association. Raman had produced credible work in his discipline, and the Indian Association for the Cultivation of Sciences published his early autobiographies. These addressed the maintenance of vibrations and the theory of violin-family musical instruments. He presented a paper on the "Molecular Diffraction of Light" in 1922, marking the beginning of a series of studies with his associates that eventually resulted in the discovery of the radiation effect, which bears his name. He won the 1930 Nobel Prize in Physics for this work. He and Suri Bhagavantam made the quantum photon spin discovery in 1932.

Raman lost consciousness in his lab at the end of October 1970. He pulled through and requested to be moved from the hospital to his institute's grounds. On November 21st, 1970, he passed away. His life served as an example of how hard work, dedication, and patience can lead to success. A new era of higher science began with him, and he set the example for others to follow.

• C V Raman Biography

Writing a Biographical Essay of a Historical Figure

Sir Chandrasekhara Venkata Raman, was an Indian physicist who won the Nobel Prize in Physics in 1930 for his work on light scattering and the discovery of a new form of scattering called Raman scattering or the Raman effect. The compositions of solids, liquids, and gases can all benefit from this effect. It can also be used to diagnose diseases and track manufacturing processes. 

Biography is an account of a person’s life by another person. It is a descriptive work written in detail. Biographical pieces can be in various forms, like a video or book and they can be of any length, like a book or an essay. An authorized biography is written with the permission of the subject and an unauthorized one is not. However, biographies of historical figures written for purely academic purposes do not require consent from the subject or people who hold the rights of consent for the subject.

Choosing the Right Level

Biographies can be written by students of all classes. The higher the class, the more details go into the essay. The biography by a fifth-grader will be smaller and less detailed than that written by a ninth-grader. The demand for making it more interesting and decorating it with aptly placed figures of speech grows with grade.

Choosing the Right Source

Biography is not fiction or a made-up story. It is the arrangement of boring dates and facts into a beautiful landscape that would be the subject’s life. For the facts to be accurate and true, trustworthy sources must be consulted, like a known book or reliable websites that contain life information.

Choosing the Right Information

Having selected the right source of information, it can get mind-boggling to choose what information to keep and what not to mention in the essay. It is better to have too much information than too little so that the best out of them can be chosen. A biography should answer some basic questions about the person. The place and date of his birth and death. Information about his immediate family. Important milestones of his life, like schooling, occupation, marriage, kids, appointments, or discoveries. His accomplishments during his lifetime. And then the legacy he leaves behind, like his impact on society or education and the historical significance.

How to Arrange the Information?

Biographies are descriptions of someone’s life, so setting the tone and making it sound interesting relies freely on the writer’s shoulders. The student can make life sound fun and lively, or gripping and intense. This is where the talent of a writer shines through, so use all of the writing tools at hand and make the best of them.

The Person Behind the Facts

The personality of the subject should shine through the essay. Select appropriate adjectives to build upon the character of the person. If interesting anecdotes highlight the kind of person he was, use them to build upon his personality.

Legacy in Conclusion

The achievement of his life and his notable works need to be mentioned, as well as how he affects posterity. In conclusion, the importance of his work and legacy should be highlighted.

It should be remembered that however tempting it feels to include interesting details and fun facts, the word limit should be kept in mind. This is what should rule which facts go and which do not in the essay. The introduction, body, and conclusion need to be clearly arranged. A biographical essay is not a story-telling spree, so the spirit of an essay should be intact.

The best essays are easy to read and the flow from one part to another is seamless. It might sound contradictory to keep a seamless flow while keeping the three parts of an essay demarcated, but it is not impossible and this is the delicate balance that can only be achieved by persistent practice. Language is not much different from Maths or Science in this aspect – practice makes perfect.

About C V Raman’s Family and Background

Chandrasekhara Venkata Raman was born to a Tamil Brahmin family in Tiruchirapalli, Tamil Nadu, on November 7, 1888. Raman's forefathers were agriculturists who settled in the Tanjore district near Porasakudi Village and Mangudi. Chandrasekhara Iyer, his father, attended a school in Kumbakonam and graduated with honours in 1881. He eventually earned a Bachelor of Arts degree in Physics from Tiruchirapalli's Society of the Promotion of the Gospel College in 1891. In the same college, Chandrasekara became a lecturer. He married Parvathi Ammal after passing the Matriculation exam and they had eight children: five sons and three daughters. Chandrasekaran, Raman's father, moved to Visakhapatnam when he was four years old to work as a lecturer at Mrs. A.V. Narasimha Rao College. He taught Physics, arithmetic, and physical geography at the university. Chandrasekaran was regarded as physically and mentally powerful due to his involvement in athletics, physical culture, and Indian Carnatic music, among other things. Raman, unlike his father, was not physically powerful, but he was a brilliant thinker. He excelled in school and displayed early signs of exceptional ability, receiving praise from his teachers as well as numerous prizes and scholarships. While still in school, Raman developed an interest in Physics. He once designed a dynamo on his own and was fascinated with how physical principles and machines worked. C. V. Raman graduated from high school at the age of eleven, receiving first place in the Matriculation Examination (top marks). He then enrolled in the AVN College to prepare for the Intermediate Exam. He received more accolades this time, and he received top scores on the university test. In 1903, he received a scholarship to study for a BA degree at the Presidency College in Chennai (then Madras), where he was the youngest student. At the time, the Presidency College was the best in Southern India. When Raman was in college, the majority of his professors were Europeans. Raman's interest in Physics grew even stronger during this period, and he also developed a strong liking for English. Raman earned first place in the university's BA exams in 1904, and gold medals in English and Physics. Raman's teachers encouraged him to continue his education in England, but the Madras Civil Surgeon refused, arguing that the young Raman was too weak to endure the English climate. Raman, on the other hand, completed his MA in Physics at Presidency College and did not travel abroad until he was thirty-three years old.

About C V Raman’s Early Career and Marriage

In January 1907, Raman sat for and passed his Master's examination, earning top marks and a slew of awards and prizes. While he desired to focus on science (particularly research), there were no research opportunities in India (specifically for Indians). Owing to his deteriorating health at the time, he was unable to travel to England. As a result, Raman's thoughts turned to work for the government, which is known to be clean, stable, and even prestigious. Even in this situation, he desired to enter the prestigious Indian Civil Service (ICS), the highest level of government service, but this meant training in England and taking the exam there—an option that was also ruled out due to medical reasons. The Financial Civil Service (FCS), where Raman's brother C.S. Iyer was already a member, which was his next preference. The FCS served as a forerunner to today's Indian Audit and Accounts Service. Raman passed the FCS examination in 1907 and married Lokasundari before taking up an official job. This period of his life unfolded unusually. Typically, parents arranged Indian marriages, which includes finding a suitable horoscope match for their infant. This included looking at the positions of the stars on their birth date, as well as other horoscopic statistics.  The boy and his parents then pay a visit to the girl's house to see if she likes them; during this period, the girl is normally asked to give a musical performance. The date for their marriage is fixed if all arrangements are in agreement and the girl's family provides adequate dowry. Raman's marriage went in a different direction. Mr. Ramaswamy Sivan, a freemason, theosophist, and radical thinker, was a friend of Raman's as a college student. Mr. Sivan's house was a frequent stop for Raman, and one day he heard music from an Indian classical instrument, the veena, played by Lokasundari, Sivan's sister-in-law, who was visiting from Madurai. Lokasundari was a natural at playing the veena, and Raman was instantly drawn to her. Sivan discussed this idea with Raman, who immediately accepted it since Lokasundari was of marriageable age at the time and her family was looking for a suitable groom. Raman then continued to seek permission from his parents. However, it was later discovered that Lokasundari, thought of the same caste as Raman (Brahmin), belonged to a separate subset—a match that was strictly forbidden at the time. Raman's father, who is a rather liberal man, agreed that Raman could choose his bride, even if she came from a different subset. The rest of the family, including Raman's mother, was unhappy, however. Despite these challenges, Raman followed his heart and kept on doing things his way. In mid-1907, Raman was appointed Assistant Accountant-General in Calcutta, even though he was still a teenager. His pay, including the marriage allowance, was Rs. 400 at the time. Raman and Lokasundari set out for Calcutta, the capital of British India at the time. Raman took advantage of Calcutta's vibrant and scientific environment, allowing him to fully articulate his scientific creativity—Calcutta was then regarded as the East's premier science city. Raman was sent to Nagpur and Rangoon in addition to Calcutta; no matter where he was posted, Raman still found a way to perform experiments at home.

C V Raman Contribution to Science

Raman productively used the time he had with Professor Jones while studying Physics at Presidency College, designing and creating experiments to address the boundless questions he had. Only the most basic laboratory instruments (enough for classwork) were available in the Physics lab at the time, but Raman made use of them all. Raman's questions were frequently those for which there were no answers in the literature. As a result, the nature of science came naturally to him, prompting him to perform experiments throughout his life. Raman experimented with asymmetric diffraction of light though he was well aware of light in a wave shape and the principle of diffraction. Professor Jones was given his observations on this experiment, which he collected and gave to him for feedback. Professor Jones, on the other hand, remained silent for many months. Raman was aware of the Philosophical Magazine at the time, possibly those subscribed to by the Connemara Public Library, which was about five kilometers from Presidency College (it is not certain how Raman came to know of this magazine). This paper was written in 1906, and Raman, who was only 18 at the time and had not yet graduated from high school, was the sole author with no acknowledgments. Raman's achievement was all the more remarkable because Presidency College was not a research institution, and Raman's paper was the first to emerge from there. Almost immediately after Raman's first publication, Johns Hopkins University's R.W. Wood published another. Wood later sent a cable to Nature announcing the Raman Effect's discovery. Raman left the government in 1917 to take up the newly established Palit Professorship in Physics at the University of Calcutta. Simultaneously, he continued his study at the IACS, where he eventually rose to the position of Honorary Secretary. Raman referred to this period in his career as his "golden age." At the IACS and the University of Calcutta, he was surrounded by a group of gifted students. In 1929, he presided over the 16th session of the Indian Science Congress. Raman worked on the acoustics of musical instruments in addition to his Nobel Prize-winning work on light scattering. Based on superposition velocities, he developed a theory of transverse vibration of bowed strings. In comparison to Helmholtz's method, this does a great job of describing bowed string vibration. He was also the first to explore the harmonic essence of Indian drum sounds like the tabla and mridangam. Raman was appointed director of the newly established Indian Institute of Science (IISc) in Bangalore in 1933. The IISc was established in 1909 with the aim of conducting original research and providing science and engineering education. Before Raman's appointment, all of IISc's directors, as well as the majority of its faculty, were British. He remained a Professor of Physics for another two years. The new government of Independent India named him the country's first National Professor in 1947. In 1948, he retired from the Indian Institute of Science and a year later founded the Raman Research Bangalore, Karnataka, where he served as director until he died in 1970.

C V Raman’s Discovery

Raman was awarded the Nobel Prize in Physics in 1930 for his research on light scattering and the discovery of the Raman effect. The inelastic scattering of a photon is known as "Raman scattering" or "Raman effect." This phenomenon is the basis for Raman spectroscopy.

What led to C V Raman’s Invention of Raman Effect?

C V Raman Discovery of the Physics of Musical sound- Understanding the Physics of musical Sound was one of Raman's passions. The Sensations of Tone by Hermann Von Helmholtz, which he came across when he entered IACS, inspired him. Between 1916 and 1921, he researched and published a lot of his observations. Based on the superposition of velocities, he developed the principle of transverse vibration of bowed string instruments. The wolf tone in violins and cellos was one of his earliest experiments. He investigated the acoustics of various violins and related instruments, as well as water splashes and Indian stringed instruments. "Experiments with mechanically-played violins" was one of his works. C V Raman Discovery behind the Blue colour of the sea- In 1919, Raman began investigating light scattering as part of his broadening foray into optics. His first amazing discovery was the mechanics of seawater's blue colour. In September 1921, he reflected on the Mediterranean Sea's blue colour while sailing home from England on the S.S. Narkunda. He tested the seawater with basic optical instruments, including a pocket-sized spectroscope and a Nicol prism. No.56 Lord Rayleigh's explanation in 1910, "The much-revered dark blue of the deep sea has little to do with the colour of water, but is the blue of the sky seen by refraction," was the strongest of many theories on the colour of the sea. C V Raman Inventions: Most photons are elastically dispersed as light is scattered from an atom or molecule. The incident photons have the same energy (frequency) as scattered photons, and therefore the same wavelength. Excitations of optical frequencies distinct from, and normally lower than, the frequency of the incident photons scatter a small fraction of scattered light (roughly one in ten million photons). Raman scattering may occur in gas when a molecule's vibrational, rotational, or electronic energy changes. "The character of scattered radiations allows us to obtain an insight into the ultimate structure of the scattering," Raman explained. Raman published his thesis on "Molecular Diffraction of Light" in 1922, the first of a series of investigations with his collaborators that eventually led to his discovery of the radiation effect that bears his name (on February 28, 1928). In 1928, C. V. Raman and K. S. Krishnan, as well as Grigory Landsberg and Leonid Mandelstam, independently identified the Raman effect. Raman's discovery was hailed by physicists as evidence of the quantum theory. The vibrational Raman effect is of primary interest to chemists. The Raman Effect was named a National Historic Chemical Landmark by the American Chemical Society in 1998, in recognition of its importance as a method for studying the structure of liquids, gases, and solids. The Raman Effect is distinct from the fluorescence mechanism. The incident light is completely absorbed in the latter case, and the system is transferred to an energetically excited state from which it can only transition to various lower states after a certain period (resonance lifetime). Both processes emit a photon with a different frequency than the incident photon, and the molecule is brought to a higher or lower energy level. However, the Raman Effect can occur for any frequency of incident light, which is a significant difference. The Raman Effect, in contrast to the fluorescence effect, is not a resonant effect.

He was elected a Fellow of the Royal Society in 1924. He did, however, resign from the fellowship in 1968 for unknown reasons, making him the only Indian FRS to do so. In 1929, he was the President of the Indian Science Congress's 16th session. From 1933 until his death, he was the first President of the Indian Academy of Sciences. In 1961, he was elected to the Pontifical Academy of Sciences.

Though still employed by the Indian Finance Service, Raman won the Curzon Research Award in 1912. While still working for the Indian Finance Service, he received the Woodburn Research Medal in 1913. The Accademia Nazionale delle Scienze in Rome awarded him the Matteucci Medal in 1928. He was knighted in 1930. The Viceroy of India, Lord Irwin, conferred him a Knight Bachelor in a special ceremony at the Viceroy's House (now Rashtrapati Bhavan) in New Delhi after his inclusion in the 1929 Birthday was postponed. He was awarded the Nobel Prize in Physics in 1930 for "research on light scattering and the discovery of the phenomenon named after him."He was the first Asian and non-white person to win a Nobel Prize for Science. Rabindranath Tagore (another Indian) had previously won the Nobel Prize for Literature in 1913. He was awarded the Hughes Medal of the Royal Society in 1930. The Franklin Institute in Philadelphia awarded him the Franklin Medal in 1941. He received the Bharat Ratna award in 1954. (along with politician and former Governor-General of India C.
