What don't you understand here:Ebi Rogha said:Summary:: When studying incidental photons, when should I use elastic scattering (Rayleigh scattering) and when inelastic scattering (Raman Scattering)?
What is the application of each of them?
I do not understand when we use elastic approach and when use inelastic approach for:PeroK said:What don't you understand here:

Is this an idle question? Or, is there some specific reason for asking?Ebi Rogha said:I do not understand when we use elastic approach and when use inelastic approach for:
1- an incident light
2-an incident single photon
Rayleigh scattering is the scattering of light by particles that are much smaller than the wavelength of the light, while Raman scattering is the inelastic scattering of light by molecules. In Rayleigh scattering, the scattered light has the same frequency as the incident light, while in Raman scattering, the scattered light has a different frequency due to the energy exchange with the molecules.
Rayleigh scattering is responsible for the blue color of the sky during the day, as the shorter blue wavelengths are scattered more than the longer red wavelengths. Raman scattering, on the other hand, does not significantly affect the color of the sky as it is a much weaker process compared to Rayleigh scattering.
Yes, Rayleigh scattering is used in many applications such as atmospheric remote sensing, optical communications, and particle size analysis. Raman scattering is commonly used in spectroscopy to identify and analyze chemical compounds in a sample.
The intensity of Rayleigh scattering is primarily determined by the size of the scattering particles and the wavelength of the incident light. For Raman scattering, the intensity is affected by the strength of the molecular vibrations and the frequency of the incident light.
Rayleigh scattering and Raman scattering are both types of light scattering, but they differ in the mechanism and the type of particles/molecules involved. They can also occur simultaneously in a sample, with Rayleigh scattering being the dominant process due to its higher intensity.
