Character introduction

Raman, Indian physicist, 1888-1970, won the 1930 Nobel Prize in Physics for his research work on light scattering and the discovery of the Raman effect. He is the first person in Asia to win the Nobel Prize.

He discovered that the frequency of monochromatic light changes after it is scattered by media molecules, which is called the combined scattering effect. This discovery was quickly recognized. The Royal Society officially called it "one of the three or four most outstanding discoveries in experimental physics in the 1920s."

Glossary

1. Inert gas: Also known as rare gas, the chemical properties of rare gas are very inactive and are not prone to chemical reactions with other elements. They are called "inert gases".

2. Reflection, refraction, and scattering: When light passes through smoke, it will encounter many small solid particles and small liquid beads, causing frequent reflection and refraction. Due to the uncertainty of smoke particles, the direction and position of the light emitted are greatly deflected, and scattering occurs.

3. The Nobel Prize was established with part of the legacy (31 million Swedish kronor) of Alfred Bernhard Nobel, the famous Swedish chemist and inventor of nitroglycerin dynamite. The Nobel Prize is divided into five categories: physics, chemistry, physiology or medicine, literature, and peace. It is awarded with the annual interest or investment income of the fund to those who have made significant contributions to mankind in these fields in the previous year.
