Sir Chandrasekhara Venkata Raman

C.V. Raman won the Nobel Prize for an important research in the field of optics (light). Raman had found that diffused light contained rays of other wavelengths-what is now popularly known as Raman Effect. His theory explains why the frequency of light passing through a transparent medium changes.

C. V. Raman was born at Tiruchirapalli in South India on November 7th, 1888.

Raman entered Presidency College, Madras, in 1902, and in 1904 passed his B.A. examination, winning the first place and the gold medal in physics; in 1907 he gained his M.A. degree, obtaining the highest distinction.

Raman spent 15 years as a Professor in Physics at Calcutta University (1917-32), and 15 years as a Professor in Physics at the Indian Institute of Science, Bangalore (1933-48). In 1948, Raman became the Director of the Raman Institute of Research at Bangalore, established and endowed by himself.

On February 28, 1930, Chandrasekhar Venkata Raman discovered the radiation effect involving the inelastic scattering of light that would bear his name- the Raman effect - and which would win him Asia's first Nobel Prize in any Science subject, in 1930.

Raman's research interests were in optics and acoustics - the two fields of investigation to which he dedicated his entire career. The main investigations carried out by Raman were: his experimental and theoretical studies on the diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies (published 1934-1942), and those on the effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light.

Raman was elected a Fellow of the Royal Society early in his career (1924), and was knighted in 1929. Besides, Raman was honoured with a large number of honorary doctorates and memberships of scientific societies. C. V. Raman passed away in 1970.
