Raman effect definition
Raman scattering, also known as Raman scattering, was discovered by Indian physicist Raman in 1928. It refers to the phenomenon that the frequency of light waves changes after being scattered. In 1930, the Nobel Prize in Physics was awarded to Raman (Sir Chandrasekhara Venkata Raman, 1888-1970), who was working at the University of Kolkata, India, in recognition of his research on the scattering of light and discovery of the law named after him.
