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.Credit: iStock
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.Credit: iStock
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.Credit: iStock
Applications in Science
This discovery provided a new way to study the vibrations of atoms and molecules and opened up a new field of spectroscopy.Credit: iStock

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.Credit: iStock
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.Credit: iStock
CV Raman's contributions
Research in acoustics: CV Raman made contributions to the field of acoustics as well, particularly in the area of ultrasonic vibrations. He developed a method for measuring ultrasonic frequencies and used this method to study the properties of crystals.Credit: iStock
