National Science Day

  • It is celebrated to commemorate the discovery of the ‘Raman Effect’, which led to Sir C.V. Raman won the Nobel Prize in Physics in 1930.
  • National Council for Science & Technology Communication (NCSTC), Department of Science and Technology (DST) acts as a nodal agency to support, catalyze and coordinate celebration of the National Science Day throughout the country.
  • NCSTC has supported various programmes countrywide by supporting its State S&T Councils & Departments for organization of lectures, quizzes, open houses, etc.

What is Raman Effect

  • The Raman Effect is a phenomenon in spectroscopy discovered by the physicist Sir Chandrasekhara Venkata Raman in 1928.  
  • This was the first Nobel Prize by an Indian in the field of Science. 
  • The Raman Effect is a change in the wavelength of light that occurs when a light beam is deflected by molecules.
    • 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.
