Greatphysicist and Nobel Laureate, CV Raman was born on November 7th, 1888 atTiruchirappalli in Southern India. This year we are celebrating the 131st birthanniversary of one of the most prominent scientists. He made theground-breaking discovery called Raman effect; it is the change in wavelength,which occurs when a light beam is deflected by a molecule.
C.V. Raman was an outstanding physicist of his time and made great contributionsto the human world. But this is sad to say that not much is known about hislife beyond his work in science. On his birth anniversary, we are presentingsome important information about his life that you should know.
Asmention earlier, Raman belongs to Tiruchirappalli, Southern India. His fatherwas a lecturer in mathematics and physics. That is why, Raman was immersed in an academicatmosphere. In academics, he got a Bachelor degree in physic at the Society ofthe Promotion of the Gospel College. After studies, he joined the same collegeas a lecturer. Then, he went on to clear his MBA and then joined the governmentservice. In 1933, Raman became a professional at the Indian Institute ofScience. He was also elected as a Fellow of the Royal Society in 1924 and wasknighted in 1929.
There,Raman started his experiments for studying the scattering of light; and henceintroduced the Raman Spectroscopy for observing the rotational, vibrational andother low-frequency modes in a system. It is mainly used in chemical laboratoriesand works as the fingerprint for the substance from which the light isscattered. Apart from his amazing discoveries in physics, Raman wasinstrumental in setting up of many prominent Indian research institutes. In 1947,Raman was named as the director f the Raman Research Institute.
Awards and Achievements
WhenRaman was 42 years old, he won the Nobel Prize in physics for this discovery in1930 and became the first Asian to receive the prize in the field of science.
Additionally,Raman has been honoured with many honorary doctorates and memberships ofscientific societies. He was elected a Fellow of the Royal Society early in hiscareer and was knighted in 1929.
Apartfrom awards and prize, Raman was awarded the biggest Indian reward, BharatRatna in 1954 and the Lenin Peace Prize (1957).
Everyyear, 28th February is celebrated in India as National Science Day tocommemorate Raman's discovery in 1928.
Theimportance and impact of Raman are remarkable. That's the reason, the picturesof C. V. Raman, his father Chandrasekaran, and Professor Jones (Raman's physicsprofessor) hang at the entrance of the lecture hall of the Physics Departmentof Presidency College.
OnOctober 2, 1970, Raman gave his last Gandhi Memorial Lecture, on the Cochleaand the perception of sound. On November 21, 1970, he passed away from naturalcauses in the early morning.
Evenafter death, Raman is remembered for his contribution and legacy. Ramanspectroscopy that uses the Raman Effect is a vital tool to identify and a widerange of complex materials such as biological organisms and human tissue.
