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. The Tyndall effect is used to differentiate between the different types of mixtures namely solution, colloid and suspension. For example, the Tyndall effect is noticeable when car headlamps are used in fog. The light with shorter wavelengths scatter better, thus the color of scattered light has a bluish tint. This is also the reason as to why the sky looks blue; the light from the sun is scattered and we see the blue light because it scatters better.
