Rayleigh's law of scattering
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. WebSolution. Rayleigh scattering is the scattering of light by the particles present in the atmosphere. According to Rayleigh's scattering law, the amount of scattering of the light …
