For which discovery did C.V. Raman receive the Nobel Prize in Physics?

C.V. Raman received the Nobel Prize in Physics in 1930 for his discovery of the Raman Effect, a phenomenon explaining the scattering of light when it passes through a transparent medium. Raman observed that when light interacts with molecules, a small fraction of the light changes in wavelength. This change provides vital information about the molecular structure of the material. The discovery opened new frontiers in spectroscopy, chemistry, and material science. The Raman Effect remains a cornerstone in modern research, used in medical diagnostics, chemical analysis, and even astronomy to study the composition of distant stars and planets.
