Sir Chandrasekhara Venkata Raman was an Indian physicist whose works help India to grow in Science and Technology.  He received Nobel Prize for his invention i.e. light traverses a transparent material, some of deflected light changes in wavelength. This phenomenon is known as Raman Scattering or Raman Effect.

Awards:

Raman was honoured with a large number of honorary doctorates and memberships of scientific societies.

  • He was elected a Fellow of the Royal Society early in his career (1924) and knighted in 1929.
  • In 1930 he won the Nobel Prize in Physics. In 1941 he was awarded the Franklin Medal.
  • In 1954 he was awarded the Bharat Ratna.
  • He was awarded the Lenin Peace Prize in 1957. In 1998, the American Chemical Society and Indian Association for the Cultivation of Science recognised Raman’s discovery as an International Historic Chemical Landmark.

India celebrates National Science Day on 28 February of every year to commemorate the discovery of the Raman effect in 1928.
