National Science Day is celebrated on February 28 every year in India to honour and remember the discovery of Raman Effect by the Indian Nobel laureate Chandrasekhara Venkata Raman.
On this day his ground-breaking contributions towards the field of science and technology is celebrated so that his legacy continues to be remembered and inspire following generations across the world.
CV Raman was passionate about science and education
The eminent scientist from India was born in Tiruchirappalli, Tamil Nadu. He was passionate about science and education right from his childhood. After completing his Bachelor’s in Physics from Chennai’s Presidency College, he completed his Master’s degree from the Calcutta University and went to the UK to pursue doctorate at the University of Cambridge.

His exceptional talent and intellectual abilities led him to make many remarkable discoveries in the field of physics.
Discovery of Raman Effect
The most important breakthrough of CV Raman was made when he was working as the professor in Kolkata at the Indian Association for the Cultivation of Science in 1928. At that time he was doing experiments on the scattering of light. During his experiments he observed a phenomenon related to the scattering of light that was unknown to mankind till then. He immediately knew that this was something which would create a big revolution in the years to come.
The phenomenon which now is known as the Raman Effect demonstrated how the photons are scattered by molecules in an inelastic way thereby offering a valuable insight into the dynamics and structure of a molecule. This particular discovery made CV Raman world famous and also earned him the Nobel Prize for Physics in 1930.
He is the first Indian to receive this prestigious award. CV Raman was the pioneer researcher whose research especially related to light-matter interactions laid down the foundation for the advancements in various technological and scientific fields such as material science, telecommunications and spectroscopy.
