Rayleigh scattering and blue sky

WebThe wavelength-dependent scattering (blue light getting scattered by oxygen and nitrogen) is called Rayleigh scattering. The one non-dependent on the wavelength (light scattered by the water molecules in the clouds, causing their white color) is called Mie scattering. The strong wavelength dependence of the scattering (~λ ) means that shorter (blue) wavelengths are scattered more strongly than longer (red) wavelengths. This results in the indirect blue light coming from all regions of the sky. Rayleigh scattering is a good approximation of the manner in which light scattering occurs within various media for which scattering particles have a small size (p…
