Sir Chandrasekhara Venkata Raman (1888–1970) was an Indian physicist who won the Nobel Prize in Physics in 1930 for his discovery of the Raman Effect.

Discovered on 28 February 1928, the Raman Effect explains the scattering of light when it passes through a transparent medium (solid, liquid, or gas).

A small fraction of the scattered light changes in wavelength and energy, revealing information about the medium’s molecular structure.

This discovery revolutionized spectroscopy and led to the development of Raman Spectroscopy, a powerful tool in chemistry, physics, and material science.

First Indian Nobel Laureate in Science (1930).

Established the Raman Research Institute (RRI) in Bangalore (now Bengaluru) in 1948.

National Science Day (February 28) is celebrated in India to honor his discovery.
