Question

Name the Indian scientist who has contributed in the discovery of inelastic scattering of light by molecules.

Answer 1

Hint: The scientist who contributed to the discovery of inelastic scattering of light by molecules is known for his groundbreaking work in the field of light scattering. He published his work on the "Molecular diffraction of light" series.

Complete step by step answer:
The inelastic scattering of light by molecules is also known as the Raman effect or Raman scattering. C.V Raman discovered this phenomenon in 1928.
In this phenomenon, the inelastic scattering of light occurs due to the interaction responsible for the loss of the incident primary electron's energy. The inelastic scattering of photons by matter explains that the exchange of energy and the change in light direction.
In this effect, monochromatic light frequency is changed when it interacts with vibrational states of a molecule. As the laser resources and detectors advance, the Raman spectroscopy is developed as a highly sensitive method to probe the structure of a complicated molecule. This effect was theoretically postulated by the scientist Smekal in 1923 but later discovered by C.V Raman.
Therefore, the Indian scientist who has contributed to the discovery of inelastic scattering of light by molecules is C.V Raman

Note:
One should not confuse between the elastic scattering of light and inelastic scattering of light. The elastic scattering of the light phenomenon was given by scientist Rayleigh. It explains that the state of the molecule and photons' energy is unchanged after light scattering.
