What is the Tyndall Effect?

The Tyndall effect is referred to the phenomenon in which light is scattered by particles in a colloidal solution or in a very fine suspension. It can be seen when the light passes through the colloids or turbid substances causing the light to scatter in multiple directions.

Example: On a day when the sky is overcast, the sunlight passes through the turbid layer of the clouds, resulting in scattered, diffuse light on the ground.
