National Council for Science and Technology Communication (NCSTC) had requested Union Government to assign February 28 as the ‘National Science Day’ for India in 1986.

And after that in 2000 on February 28 the first National Science Day was celebrated.

The Raman Effect:

  • Some part of light beam after passing through a transparent medium gets scattered.
  • This miracle of trickle of light is termed as Raman Scattering and the cause of scattering is called the Raman Effect.
  • The wavelength of these scattered rays is different from that of the incident rays of light.
