National Science Day

National Science Day commemorates the discovery of the Raman Effect, for which CV Raman was awarded the Nobel Prize in Physics in 1930. His contributions to the field of physics have had a lasting impact on our understanding of light and matter, and his legacy continues to inspire scientists around the world.

A phenomenon named after CV Raman

Raman is best known for his discovery of the Raman Effect, a phenomenon that occurs when light passes through a substance and scatters in different directions.

Raman Effect

In 1928, he observed that a small portion of the light that passed through a transparent material underwent a change in wavelength and scattered at a different angle than the incident light.

How the sky gets its colour

He demonstrated that the scattering of light by particles in a liquid is responsible for the blue colour of the sky, and he also investigated the polarisation of light scattered by molecules.

Beyond Nobel Prize

Contributions to optics: CV Raman worked on a number of problems in optics, including the theory of diffraction of light, the propagation of light in turbid media, and the scattering of light by crystals.
