what is raman effect ? what is its importance
Answers
It is a phenomenon in which change in the wavelength of light occurs when a beam of light is deflected by molecules. When a beam of light travels from a dust-free transparent sample of a chemical compound, then a small fraction of the light emerges in the direction other than that of the incident light. Most of the scattered light wavelength is unchanged and in small part, if the wavelength is different from that of incident light it is due to Raman Effect.
Awards which were won by CV Raman are:
Fellow of the Royal Society (1924), Knight Bachelor (1929), Nobel Prize in Physics (1930), Bharat Ratna (1954), Lenin Peace Prize (1957) and Fellow of the Royal Society (1924).
Raman effect explains the change in wavelength of light when it gets scattered by molecules in its path.
- Excited molecules present at higher energy levels result in the scattering of photons present in the light.
- The variation in the frequency of these scattered photons contributes to different wavelengths.
Importance of Raman effect:
- Raman effect is widely used in the telecommunication industry. Transmission of information by frequency amplification is possible due to this effect.
- It is an important concept used in nanotechnological studies. It is helpful in studying DNA, proteins, atomic structure, and atomic and molecular bonds.
- Raman effect is an important concept used in fields like optics, astrophysics, etc.
