|C.V. Raman's BirthDay|
Sir Chandrasekhara Venkata Raman, FRS (7 November 1888 – 21 November 1970) was an Indian physicist whose work was influential in the growth of science in India.
He was the recipient of the Nobel Prize for Physics in 1930 for the discovery that when light traverses a transparent material, some of the deflected light changes in wavelength. This phenomenon is now called Raman scattering and is the result of the Raman effect.
