National Science Day is celebrated in our India on 28th February every year to remember the discovery of "Raman Effect" by our Indian physicist Sir. Venkata Raman in 1928. For this discovery, sir. CVRaman was awarded the Nobel Prize in Physics in 1930. National Science Day is celebrated with great passion across India on 28 February every year to salute and honor the invention of Raman effect by a physicist Indian, Sir. CVRaman on the same day i.e. 28 February 1928. The first National Science Day was celebrated on 28 February 1987. In 1986, the National Council for Science and Technology Communication (NCSTC) requested the Government of India to celebrate 28 February as National Science Day then the Government. of India accepted and declared the day National Science Day in 1986.

When a strong ray of visible or UV light illuminates a gas, liquid, or transparent solid, a small fraction of the light is scattered in all directions, the spectrum of the scattered light is found to consist of lines of the same frequencies as the incident ray called Rayleigh lines and also some faint lines of modified frequencies. These additional lines or faint lines are called Raman Lines. Each year various themes will be chosen for the celebration of National Science Day. And the main objective of the National Science Day is to provide citizens of the country with the opportunity to grow, discuss problems and implement new technologies for the development of science. The main objective is to bring together all citizens to celebrate the growth of science and technology in the country and spread a message about the importance of scientific application in people's daily lives. School and university students display various science projects to demonstrate their latest research. The celebration also includes public speeches, science film screenings, theme- and concept-based science exhibitions, radio and television talk shows, live project and research demonstrations, debates, quiz competitions, lectures and other activities.
