Have you ever wondered how bomb explosives are detected by Bomb explosive and detecting squad or drugs are detected by narcotics team or how the chemical composition of any substance is found out? The answer is
RAMAN EFFECT.
This breakthrough discovery of C.V Raman got him Nobel Prize in physics in 1930. He was the first Indian scientist to get Nobel Prize in science. To commemorate discovery of Raman Effect, National Science Day is being celebrated every year in our country since 28 February 1987.
In 1987 National Council for Science and Technology Communication (NCSTC) asked Indian government to designate 28 February as National Science Day.
Since 1999, every year focal theme is decided and the programs revolves around that particular theme. This year’s theme is “Science for the People, and People for the Science”.
What is Raman Effect?
When photons are scattered by material most of them are elastically scattered, such that they have same energy but scattered in different direction. However, there are some photons which scatter inelastically and have different and less energy than incident photons. These are Raman scattered photons. Raman Effect formed the basis of Raman spectroscopy.
Objectives of Science day:
⦁ To aware people about the application of science in everyday life
⦁ To encourage science minded people
⦁ To celebrate the contribution of scientists to science and technology
⦁ To display the work, inventions and discoveries and enlighten people about them
Today on this special occasion of National Science Day Prime Minister Narendra Modi presented the prestigious Shanti Swarup Bhatnagar prizes recognizing outstanding Indian work in science and technology. We hope and wish that someday you will be on this list.
“Success can come to you by courageous Devotion to the task lying in front of you.”
-C.V. Raman
We at eSaral truly believe in the ideology of Shri C.V. Raman. When you learn and understand the nuances of science with full devotion and do not lose your curiosity ever, then it will be called success in true sense.
