National Science Day 2023 today: Role of CV Raman, what is Raman Effect?
National Science Day is widely known each 12 months on February 28 to mark and understand the contributions of scientists toward the improvement of the u . s .. On this day, in 1928, Indian physicist Chandrasekhara Venkata Raman, popularly called CV Raman, made an critical discovery withinside the subject of spectroscopy, which became later named after him, the Raman Effect. For his work, CV Raman became presented the distinguished Nobel Prize in Physics in 1930.
Raman Effect, additionally called Raman Scattering, is the alternate withinside the wavelength of mild that takes place whilst it’s far deflected via way of means of molecules. A mild beam traversing via a obvious pattern of a chemical compound sees a small fraction of the mild rising in a one of a kind route to that of the incoming beam. A small a part of that mild has a differing wavelength from the incident mild. This is due to the phenomenon called Raman Effect.
Origin
At the age of 19, CV Raman finished his masters, and had constructed a sturdy popularity as a main scientist each in India and withinside the West. In the equal 12 months, 1921, he made his first adventure to England. It became at the go back that Raman discovered the stark blue shade of the Mediterranean Sea and contemplated why it became blue as opposed to green. He postulated that the sea`s blue shade resulted from mild being scattered via way of means of the water molecules, and this speculation led him to in addition look into mild scattering.
Seven years after this adventure, Raman and his scholar KS Krishnan have been capable of show via exams that mild’s wavelength and frequency additionally alternate because it scatters via a obvious object.
How it’s far celebrated
Various applications are organised throughout the u . s . to mark the National Science Day celebrations and inspire college students to choose technology as their career. The Department of Science and Technology (DST additionally began out the National Awards for Science Popularisation in February 1987 to understand contributions to technology via awards. The National Council for Science and Technology Communication (NCSTC), Department of Science and Technology (DST), acts as a nodal business enterprise to aid and coordinate the birthday party of the National Science Day.
DST additionally began out the National Awards for Science Popularization in February 1987 to understand superb efforts in technology. The awards are given out on National Science Day and embody six categories.
