Question

Describe the main achievement of sir Chandra shekhar Venkat Raman.

Answer 1

Hint: Here we describe Venkat Raman, sir Chandra shaker, as we know the concept of Raman effect.so, we first define a scientific achievement, then we define his experiment, and finally, we describe his life achievement.

Complete answer:
Given by,
Sir C. V. Raman's scientific accomplishments are as follows:
By moving sunlight through water and fragments of ice, Sir C.V. Raman conducted experiments on the dispersion of light. He clarified that the dispersion of sunlight was the source of the blue color of the sea. In $1906$, he published a research paper on diffraction when he was an M.Sc.
Through some transparent substances, he passed monochromatic mercury arc rays and gained a spectrum on an ordinary spectrograph. He saw the spectrum of new lines and named them Raman lines. For his work on the dispersion of light and the discovery of the Raman effect, he won the $1930$ Nobel Prize in Physics and became the first Indian to win a Nobel Prize in science.
 He passed monochromatic rays of mercury arc through some transparent substances and obtained spectrum on an ordinary spectrograph. He saw new lines in the spectrum and named them Raman lines. A scientist par excellence, Sir Chandrasekhara Venkata Raman, the Indian physicist who made his motherland proud by becoming the first Indian to win the Nobel Prize in Physics, was intrigued by the blue color of glaciers and the Mediterranean Sea and wanted to unravel the mystery of why water, a colorless liquid, appeared blue to the eyes.
A series of experiments on the dispersion of light began, eventually leading to what became known as the 'Raman Effect' for which he won the Nobel Prize in Physics. Raman's effect helped to understand a substance's molecular structure. After the discovery of laser rays, a great deal of research work was done on the Raman effect.
In Bangalore, he established the Raman Research Institute and continued his research work there throughout his life. Even as a child, he showed a brilliant mind and passed his matriculation exam at a much younger age compared to other students. As the son of a mathematics and physics lecturer, from the very beginning, the young Raman was exposed to an academic environment. He was deeply interested in research throughout his academic days.

Note:
Even when he was a student, he began his research on optics and acoustics. Although he began his career as a Deputy Accountant General, he was still unable to stay away from research, often spending entire nights discovering new things in the field of physics.
