WebWhat is scattering and its types? It is of two types, elastic scattering, and inelastic scattering. Rayleigh and Mie's scattering are associated with elastic scattering and Raman's scattering is associated with inelastic scattering. The scattering of light is dependent on two factors, the wavelength of the light scattered and the size of the ... WebScattering. Scattering is the process of absorption and then re-emission of light energy. In scattering, light spreads in all directions. The air molecules of size smaller than the wavelength of incident light absorb the energy of incident light and re-emit it without change in its wavelength. Intensity of scattered light is a function of the ...

WebRayleigh scattering: 2 π r/ λ <<1, and the refractive index m is arbitrary (applies to scattering by molecules and small aerosol particles) Rayleigh-Gans scattering: (m –1) <<1 (not useful for atmospheric applications) Mie-Debye scattering: 2 π r/ λ and m are both arbitrary but for spheres only (applies to scattering by aerosol and cloud ... WebA typical cross-section for Rayleigh scatter is 10-28 cm2 sr-1. Because Rayleigh depends upon the fourth power of the frequency, the value will vary a bit. A typical cross-section for Raman scatter is 10-30 cm2 sr-1. Again the exact value will depend upon the excitation frequency and distance from the absorption band.
