WebRayleigh's scattering law. The amount of scattering is inversely proportional to the fourth power of the wavelength. This is known as Rayleigh scattering. As sunlight travels through the earths atmosphere, it gets scattered by the atmospheric particles. Light of shorter wavelengths is scattered much more than light of longer wavelengths.
