Solution

The correct option is C
Tyndall effect

The phenomenon of light scattering by particles in a colloid or particles in a very fine suspension is known as Tyndall effect. It is named after the 19th-century physicist John Tyndall. Dispersion is the separation of white light into different colours or of any radiation according to wavelength. Rayleigh scattering is the elastic scattering of light.
