Rayleigh scattering.<\/p>\n<p>Rayleigh scattering is the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength. Sunlight is scattered by the tiny molecules of air in Earth&#8217;s atmosphere. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.<\/p>\n<p>Mie scattering is the scattering of electromagnetic radiation (of which light is a form) by particles of a comparable wavelength.

It is caused by the interaction of the radiation with particles that are much smaller than the wavelength of the radiation.
