Indian National Science Day is celebrated across the country through various activities and events aimed at promoting scientific awareness and education. Some common ways of celebration include:
Several government and non-government organizations play a crucial role in organizing and promoting Indian National Science Day. The Ministry of Science and Technology, along with agencies like the Department of Science and Technology (DST), Council of Scientific and Industrial Research (CSIR), and Indian National Science Academy (INSA), collaborate to coordinate nationwide celebrations and activities.
Sir Chandrasekhara Venkata Raman, commonly known as C.V. Raman, was an eminent Indian physicist born on November 7, 1888, in Tiruchirapalli, British India (now in Tamil Nadu, India). He made significant contributions to the field of physics, particularly in the study of light scattering, molecular spectroscopy, and the behavior of light in transparent materials.
The Raman Effect, discovered by C.V. Raman in 1928, refers to the inelastic scattering of light by molecules, leading to changes in the energy and wavelength of the scattered photons. This phenomenon, based on the interaction between light and matter, provides valuable insights into the vibrational and rotational modes of molecules, thereby revolutionizing the field of spectroscopy and paving the way for numerous applications in chemistry, physics, and materials science.
