Reading Time: 2 minutes

Have you heard about the Raman Effect? Raman Effect UPSC is the most famous light scattering effect which was discovered in 1928. This light phenomenon happens when a particular type of energy, such as light or sound waves, interacts with a material.

About Raman Effect UPSC

Raman effect is usually concerned with the scattering of light, especially in the presence of tiny or small particles like dust. When the light is scattered it further leads to color change due to the excitation of energy molecules. This effect is used in various fields, including chemistry, physics, and engineering.

What Are The Raman Effects In Terms of Visible Light?

The Raman Effects in terms of visible light include the scattered light and the generated heat. The scattered light causes the appearance of colors that are opposite of the original color. The generated heat causes the molecules to vibrate and create sound.

What Are The Raman Effects In Terms of Infrared Light?

Lights have a different effect here we will see the Raman effects with respect to infrared light presence. The scattered light causes the appearance of colors that are the same as the original color. The thermal emission causes the molecules to vibrate and create heat.

Raman Effects with respect to Ultraviolet Light

The Raman Effects in terms of ultraviolet light include scattered light and fluorescence. The scattered light causes the appearance of colors that are different than the original color. The fluorescence causes the molecules to glow and create light.

What is the exact cause of the Raman Effect?

The Raman Effect is caused by the way light reflects off matter. Light waves have energies to split or scatter the molecules within the material. The energy of these scattered waves is different than the original wave, and this difference in energy is what causes the Raman Effect.

Who is CV Raman?

CV Raman was an Indian physicist who made brilliant discoveries in the field of science. His complete name was Sir Chandrasekhara Venkata Raman. He won various awards for his discovery like the Nobel prize, Bharat Ratna, Franklin medal, Matteucci medal, Hughes medal, and many more. Consistently public science day is praised on February 28 in recognition of CV Raman.

Application or Uses of Raman Effect UPSC

  • The Raman Effect can be used to see tiny details in objects and to understand how materials interact with other materials. For example, if you shine a laser beam at a solid sample of matter, some of the light will scatter off the molecules in the sample. If you then measure how much light is scattered in different directions, you can use this information to determine what kind of atoms are present in the sample and how they are arranged.
  • Raman spectroscopy is also used in detecting various components, detecting quality control, and diagnostics of cancerous cells in patients.
  • Raman scattering effect is also used in identifying the structure and chemical composition of any matter whether it is solid-liquid, slurry, powder, or anything.
