Learn about the phenomenon of scattering of light , how it depends on the size and wavelength of the particle, and the types of scattering such as Rayleigh, Mie, and Raman. Find out why the sky is blue, the sun is red, and the clouds are white due to scattering of light . The theory states that shorter wavelengths of light , such as blue light, are scattered more easily by atmospheric particles, while longer wavelengths, like red light, pass through with less scattering. When light passes from one medium to another, say air, a glass of water, then a part of the light is absorbed by particles of the medium, preceded by its subsequent radiation in a particular direction. This phenomenon is termed a scattering of light . Scattering is the deviation of radiation or particles from a straight trajectory by non-uniformities in the medium. Learn about different types, effects, and theories of scattering , such as light scattering , particle scattering , and multiple scattering .
