In 1986, the National Council for Science and Technology Communication (NCSTC) asked the Government of India to pronounce February 28 as National Science Day, for which the then Government accepted and declared the day as National Science Day. The first National Science Day was celebrated on February 28, 1987.

What is Raman effect ?

Raman Effect is a change in the wavelength of light that occurs when a light beam is deflected by molecules. When a beam of light traverses a dust-free, transparent sample of a chemical compound, a small fraction of the light emerges in directions other than that of the incident (incoming) beam. Most of this scattered light is of unchanged wavelength. A small part, however, has wavelengths different from that of the incident light; its presence is a result of the Raman Effect.

Objective to celebrate

The basic objective to celebrate National Science Day is to propagate the message of importance of science and its application among the people in their daily life. It is also celebrated to discuss all the issues and implement new technologies for the development in the field of science and to encourage the people as well as popularize the science and technology.

The event is now celebrated all over the country in schools, colleges, universities and other academic, scientific, technical, medical and research institutions. The celebration also includes public speeches, radio, TV, science movies, science exhibitions based on themes and concepts, watching the night sky, live projects, research demonstration, debates, quiz competitions, lectures, science model exhibitions and many more activities.
