Raman Effect by Sir C.V. Raman

Raman Effect by Sir C.V. Raman

 

Sir Chandrasekhara Venkata Raman: (07-09-1888 to 21-09-1970).

A new type of molecular scattering entirely different from Raleigh’s scattering was discovered by Sir C.V. Raman in 1928. When an intense beam of monochromatic light is passed through a substance, the light is scattered and the scattered light contains other frequencies in addition to that of the incident light. This is known as Raman Effect. For the above discovery Sir C.V. Raman was awarded Nobel Prize on 10th December 1930.

India celebrates National Science Day on 28 February of every year to commemorate the discovery of the Raman Effect in 1928.
