Q. Which of the following differences is/are correct about the Rayleigh and Raman Scattering?
- While Rayleigh scattering is a form of inelastic scattering of light, Raman is a form of elastic scattering.
- While Rayleigh scattering doesn’t conserve the energy of incident particles, Raman scattering does.
- Both in Rayleigh and Raman scattering, scattered photons have the same energy as the incident photons.
Choose the correct answer using the codes given below:
Answer:
None of the above
Notes:
- Rayleigh scattering is a form of elastic scattering of light or any other electromagnetic radiation. It conserves the energy of incident particles. The particles involved are atoms or molecules. The scattered photons have the same energy as the incident photons. It does not change the chemical nature of the material in the medium through which the light passes.
- Raman scattering is a form of inelastic scattering of light or any other electromagnetic radiation. It does not conserve the energy of incident particles. The particles involved are electrons, atoms or molecules. The energy of scattered photons is either lost or increased than that of the incident photons. It can change the chemical nature of the material in the medium (especially in gases).
