Happy National Science Day 2023! Every year, National Science Day is celebrated on February 28 to remember the discovery of the ‘Raman Effect’ by Indian scientist C V Raman. The first National Science Day was celebrated on February 28, 1987. Chandrashekhara Venkata Raman, popularly known as CV Raman, was a physicist from Tamil Nadu. As National Science Day 2023 nears, here’s all you need to know about Chandrashekhara Venkata Raman, the Indian physicist whose work in the field of light scattering is famous worldwide. National Science Day 2023 Date and Theme: Know History and Significance of the Day That Marks the Discovery of Raman Effect by Indian Physicist Sir CV Raman.

Take a look at 7 Interesting facts about Chandrashekhara Venkata Raman:

  1. CV Raman received the 1930 Nobel Prize in Physics for the discovery and was the first Asian to receive a Nobel Prize in any branch of science.

  2. Using a spectrograph that he himself developed, Raman discovered that when light traverses a transparent material, the deflected light changes its wavelength and frequency. This phenomenon was subsequently termed the Raman effect or Raman scattering.

  3. Raman quit his government service and was appointed the first Palit Professor of Physics at the University of Calcutta in 1917, where he also continued his research at the Indian Association for the Cultivation of Science (IACS)

  4. In 1932, Raman and Suri Bhagavantam discovered the quantum photon spin. This discovery further proved the quantum nature of light

  5. Dr Ernest Rutherford, the scientist behind the discovery of the atomic nucleus and proton, referred to Raman's spectroscopy in his presidential address to the Royal Society in 1929.

  6. Apart from being an expert on light, Raman also experimented with acoustics. He was the first one to investigate the harmonic nature of the sound of Indian drums such as tabla and mridangam

  7. On his first death anniversary, the Indian Postal Service published a commemorative stamp of Sir C V Raman with the reading of his spectroscopy and a diamond in the background.

Raman received the 1930 Nobel Prize in Physics for the discovery and was the first Asian to receive a Nobel Prize in any branch of science. In 1954, he was honoured with India’s highest civilian award, the Bharat Ratna.
