Tyndall effect

The term Tyndall effect is usually applied to the effect of light scattering on particles in colloid systems, such as suspensions or emulsions. It is named for the Irish scientist John Tyndall. For example, the Tyndall effect is noticeable when car headlamps are used in fog. The light with shorter wave length scatters better, thus the color of scattered light has a bluish tint.
