Sir Chandrasekhara Venkata Raman FRS (/ ˈ r ɑː m ə n /; [1] 7 November 1888 – 21 November 1970) was an Indian physicist known for his work in the field of light scattering. [2] Using a spectrograph that he developed, he and his student K. S. Krishnan discovered that when light traverses a transparent material, the deflected light changes ...
Sep 17, 2024 · C.V. Raman, Indian physicist whose work was influential in the growth of science in India. He was the recipient of the Nobel Prize for Physics for the discovery of how some light changes wavelength when it traverses a transparent material in what is now called Raman scattering.

At this institute, Sir C. V. Raman discovered in 1928 that when a beam of coloured light entered a liquid, a fraction of the light scattered by that liquid was of a different color. Raman showed that the nature of this scattered light was dependent on the type of sample present.
In 1928 Venkata Raman discovered that a small portion of the scattered light acquires other wavelengths than that of the original light. This is because some of the incoming photons’ energy can be transferred to a molecule, giving it a higher level of energy.
In 1928 the Indian physicist C. V. Raman (1888-1970) discovered the effect named after him virtually simultaneously with the Russian physicists G. S. Landsberg (1890-1957) and L. I. Mandelstam (1879-1944).

Aug 9, 2024 · Raman effect, change in the wavelength of light that occurs when a light beam is deflected by molecules. The phenomenon is named for Indian physicist Sir Chandrasekhara Venkata Raman, who first published observations of the effect in 1928.
The Nobel Prize in Physics 1930 was awarded to Sir Chandrasekhara Venkata Raman "for his work on the scattering of light and for the discovery of the effect named after him"
