Which of the following was discovered by CV Raman?
The Correct answer is "Raman Effect"
The Raman Effect, named after the Indian physicist Sir C. V. Raman, is a phenomenon in physics and chemistry that involves the scattering of light when it passes through a transparent medium. It was discovered by Raman in 1928, for which he was awarded the Nobel Prize in Physics in 1930.
Here's a simplified explanation of the Raman Effect:
-
Scattering of Light: When light interacts with matter, it can be absorbed by the material or it can be scattered in different directions. Most of the scattered light has the same energy (or frequency) as the incident light, a phenomenon known as Rayleigh scattering.
-
Frequency Shift: However, a small fraction of the scattered light experiences a change in frequency. This means that the light that emerges has slightly different colors or frequencies compared to the incident light. This phenomenon is known as the Raman Effect, and the shifted light is called "Raman scattered light."
-
Vibrational Energy Levels: The Raman Effect occurs due to interactions between the photons of light and the vibrational modes of the molecules in the medium. When a photon collides with a molecule, it can transfer some energy to the molecule, causing it to vibrate at a different energy level. This results in a frequency shift in the scattered light.
-
Applications: The Raman Effect has important applications in various fields, including chemistry, physics, and biology. It is used for chemical analysis, identifying molecular structures, studying crystal structures, and even in medical diagnostics.
