National Science Day 2021: You may know that 28th February is commended as National Science Day in India yet do you know why and for what the day is praised as National Science Day. I'm likewise certain you probably found out about observed Indian Scientist Sir Chandrasekhara Venkata Raman.
On this day in 1928, he found a marvel of scattering of photons which were subsequently known as 'Raman Effect' after his name. Following two years in 1930, he got Nobel Prize for this noteworthy revelation and this was the primary Nobel Prize for India in the field of Science. To check the discovery of his acclaimed phenomenon National Science Day is celebrated in India on the day every year.
The Day Officially Declared as National Science Day?
Dr CV Raman formally said on February 28, 1928, that he has invented the 'Raman Effect.' He was granted the Nobel Prize in Physics in 1930 for this significant revelation. The National Council for Science and Technology Communication (NCSTC) proposed the central government that National Science Day ought to be commended on February 28 consistently to check this revelation. From that point onward, the Government of India acknowledged that proposition and the main National Science Day was commended on February 28, 1987.
The motive of National Science Day
The fundamental reason for this day is to move students to new studies, pull in them to science, and make them mindful of science and logical achievements. Many performances are coordinated on this day identified with scientific exercises.
What is the Raman Effect?
Raman Effect is a phenomenon in spectroscopy found by the prominent physicist Sir Chandrasekhara Venkata Raman in 1928. after two years in 1930, he got Nobel Prize for this extraordinary discovery and this was the first Nobel Prize for India in the field of Science. while working in the research centre of the Indian Association for the Cultivation of Science, Kolkata.
Raman Effect is an adjustment in the frequency of light that happens when a light bar is avoided by atoms. At the point when a light emission navigates a residue-free, straightforward example of a substance compound, a little part of the light arises in bearings other than that of the episode (approaching) bar. The greater part of this dispersed light is of unchanged wavelength. A little part, notwithstanding, has wavelengths not quite the same as that of the occurrence light; its essence is an aftereffect of the Raman Effect.

About C.V.Raman| C V Raman History
Chandrasekhara Venkata Raman was born at Tiruchirappalli in Southern India on November 7th, 1888. His father was a teacher in mathematics and physics so that from the first he was involved in an academic environment. He started Presidency College, Madras, in 1902, and in 1904 passed his B.A. examination, winning the first place and the gold medal in physics; in 1907 he got his M.A. degree, obtaining the highest distinctions.
According to Britannica, After earning a master’s degree in physics at Presidency College, University of Madras, in 1907, Raman became an accountant in the finance department of the Indian government. He became professor of physics at the University of Calcutta in 1917. Studying the scattering of light in various substances, in 1928 he found that when a transparent substance is illuminated by a beam of light of one frequency, a small portion of the light emerges at right angles to the original direction, and some of this light is of different frequencies than that of the incident light. These so-called Raman frequencies are the energies associated with transitions between different rotational and vibrational states in the scattering material.
He was the recipient of the Nobel Prize for Physics in 1930 for the discovery that when light traverses a transparent material, some of the light that is deflected changes in wavelength.
Sir Chandrasekhara Venkata Raman – died on November 21, 1970.
C.V. Raman Essay For School Students
CV Raman held the first person to win a Nobel Prize from the Asian country. He earned the honour for his work on the invention of the Raman Effect and scattering of light. Nobel Prize is one of the greatest honour and recognition for a scientist.
CV Raman pseudonym Chandrasekhara Venkata Raman was born on 8 November 1888 in Tiruchirappalli (then, Madras). He is the only Nobel Laureate from India, to be conferred the Nobel Prize in physics. His father was a lecturer in Visakhapatnam, where he did his schooling. Raman joined the Financial Civil Services at Calcutta in 1907, as an Assistant Accountant-General.
Later in his life, he attended various tests as a great physician. He was the man behind the ground-breaking work of discovering the Raman Effect. He also expelled experiments in the field of light scattering. All of these earned him the 1930 Nobel Prize for Physics. He received the Nobel prize in a record time of two years, because of the practical significance of his discovery.
Some Inspirational CV Raman Quotes
- -"The whole edifice of modern physics is built upon the fundamental hypothesis of the atomic or molecular constitution of matter."
- - "I strongly believe that fundamental science cannot be driven by instructional, industrial and government or military pressures "
- -"If someone judges you, they are wasting space in their mind…Best part, it’s their problem."
- - "Success can come to you by courageous devotion to the task lying in front of you."
- - You can’t always choose who comes into your life but you can learn what lesson they teach you
- -Treat me right and you will see the light…Treat me wrong and you will be gone!!
- - Ask the right questions, and nature will open the doors to her secrets.
- - I am the master of my failure… If I never fail how will I ever learn.
