Historical Event on 11/21/1970
Sir Chandrasekhar Venkata Raman, great Indian physicist, passed away early morning at Bangalore, Karnataka. His work was influential in the growth of science in India. He was the recipient of the 1930 Nobel Prize for Physics for the 1928 discovery now called Raman scattering which is a change in frequency observed when light is scattered in a transparent material. When monochromatic or laser light is passed through a transparent gas, liquid, or solid and is observed with the spectroscope, the normal spectral line is associated with it lines of longer and of shorter wavelength and this is called the Raman spectrum. Thus the Raman effect is applied in spectrographic chemical analysis and in the determination of molecular structure.
