National Science Day

In 1986 the National council for science and Technology communication asked the government of India to designate 28 February as National Science Day which then the government accepted and declared the day as National Science Day in 1986. The first National Science Day was celebrated on February 28 1987. What is Raman Effect is a phenomenon in spectroscopy discovered by the eminent physicist Cv Raman . Raman effect is a change in the wavelength of light that occurs when a light beam is deflected by the molecules. When a beam of light traverses a dust free , transparent sample of a chemical compound ,a small fraction of light emerges in directions other than that of the incident beam . Most of the scattered light is of unchanged wavelength. A small part however has wavelengths different from that of the incident light it presence is a result of the Raman Effect. 

Purpose of the Celebration National science day is celebrated as a national festival in India every year with the following purpose 
1 To widely spread a message about the significance of scientific applications in the daily life of the people . 
2 To display all activities, efforts and achievements in the field of science for welfare of human being. 3 To discuss all the issues and implement new
technologies for the development of the science. 
4 To give an opportunity to the scientific minded citizens in the country . 
5 To encourage the people as well as to popularise the Science and Technology. So this was about national science day.
