Sir Chandrasekhara Venkata Raman

Sir Chandrasekhara Venkata Raman , 1888-1970, Indian physicist. He was professor of physics at Calcutta Univ. from 1917 to 1933. In Bangalore (Bengaluru) he directed the Indian Institute of Science and, from 1946, the Raman Institute. For his research on the diffusion of light and for his discovery of the Raman effect , he received the 1930 Nobel Prize in Physics. He is noted also for his studies of diamonds. In 1929 he was knighted.

Raman, Sir Chandrasekhara Venkata (1888–1970) Indian physicist. He greatly influenced the growth of science in India, and founded (1946) the Raman Institute. Raman received the 1930 Nobel Prize in physics for his research on the diffusion of light and his discovery of the Raman effect. This states that there is a slight change in the frequency of monochromatic (single-wavelength) light that has been scattered by passing through a transparent material. This effect appears as secondary spectral lines on each side of the primary spectral line. See also quantum theory; scattering
