  4. Drefraction of light by dust particles.

Correct answer

A. scattering of light by the colloidal particles.

Step-by-step solution

The Tyndall effect, also known as Tyndall scattering, is light scattering by particles in a colloid or a very fine suspension. Under the Tyndall effect, the longer wavelengths are more transmitted while the shorter wavelengths are more diffusely reflected via scattering. The Tyndall effect is seen when light-scattering particulate matter is dispersed in an otherwise light-transmitting medium, when the diameter of an individual particle is the range of roughly between 40 and 900 nm , i.e. somewhat below or near the
