Indigo light waves scatter next and can be seen from high altitudes such as from jet airplanes flying at normal cruising altitudes.īlue light waves scatter next, at a rate about four times stronger than red light waves. As a result, collisions cause the relatively larger wavelengths to scatter unequally, with shorter wavelengths scattering more than longer ones.Īs sunlight enters the atmosphere, much of the short violet light waves scatter first, but very high in the atmosphere and therefore not readily seen. The atoms and molecules comprising the atmospheric gasses are much smaller than the wavelengths of light emitted by the sun. The color of the sky is a result of light bouncing off gasses in the atmosphere in what is called Rayleigh scattering, named after physicist Lord Rayleigh. If sunlight is white, why is the sky blue?
