Here are some facts about CV Raman and National Science Day or Rashtriya Vigyan Divas celebrations that students should know:
Every year, India celebrates National Science Day to remember the discovery of the Raman Effect, a discovery that also earned him the Nobel Prize in 1930 in the field of Physics. During his trip to Europe in 1921, Raman became intrigued after seeing the blue colour of the Mediterranean Sea, which led him to conduct various experiments with transparent surfaces, ice blocks, and light.
Raman then noted a change in wavelength after light passed through ice cubes. Soon after, he announced his discovery to the world, and a new phenomenon was born. Raman’s work was published, and it became quite valuable in the world of science.
Later, it was due to the request by the National Council for Science and Technology Communication (NCSTC) that February 28 started being celebrated as National Science Day (NSD). CV Raman is still remembered for his remarkable discovery. He died in 1970 at the age of 82.
