Question

The inelastic scattering of photons is known as:
A. Compton effect
B. Einstein photoelectric effect
C. Raman effect
D. Hall effect

Answer 1

Hint: Use the theory of scattering of light to solve the problem.

Complete Step by Step Solution:
The inelastic scattering mechanism where frequency of scattered radiations changes according to the gain or loss of energy in accordance with the corresponding molecule or atom is known as the Raman Effect. This effect is inelastic in nature since it involves the loss in energy of the photons, which is very similar to losing kinetic energy when two objects collide.
Hence , the correct answer to the given question is option C, Raman Effect.

Additional information:
The phenomenon of scattering occurs when a light wave passes through an atmosphere of particles that get deflected from their original path and scatter in many different directions. There are three primary types of scattering- Rayleigh scattering, Mei scattering and Raman scattering effect. Rayleigh scattering is a type of uniform scattering because this type of scattering only occurs from small bodies such as atoms and molecules. This type of scattering is mainly dependent on wavelengths and the property of shorter wavelength radiations being scattered more. Mie scattering occurs as a type of non-uniform but elastic scattering since it occurs from relatively large bodies. This type of scattering also depends on wavelength and the property of shorter wavelength radiations being scattered more. Two other types of scattering are Brillouin scattering and Thompson scattering. Raman scattering is typically weak and small in comparison with Rayleigh scattering. The Raman Effect can occur in solids, liquids and gases as well.

Note: The scattering of photos by the exciting molecules that are at higher levels is known as Raman’s scattering. The scattering produces the photos with different frequencies that are dependent on the source.
