Rayleigh's law of scattering

WebThe Rayleigh scattering has to be largely suppressed in high-Q whispering-gallery modes in microspheres because of restrictions imposed on scattering angles by cavity … Webwhere α a = coefficient due to true absorption and α s = coefficient due to scattering. Lord Rayleigh (1842–1919) was the first to explain light scattering by very small particles. Rayleigh’s law of scattering (Rayleigh, 1912) says that the intensity of scattering varies: Directly with the intensity of incident light.

WebThe earth's atmosphere contains lots of particles. The dust particles scatter light but are often large enough that the Rayleigh scattering law does not apply. However the nitrogen and oxygen molecules in the earth's atmosphere are particles small enough that Rayleigh scattering applies. They scatter blue light about 10 times as much as red light. WebNov 22, 2024 · According to Rayleigh's law of scattering, the intensity of light of wavelength λ present in the scattered light is inversely proportional to the fourth power of λ, provided the size of the scattering particles is much smaller than λ. Mathematically, Thus the scattered intensity is maximum for shorter wavelength.
