"Tyndall Effect can be observed when sunlight passes through the canopy of dense forest." Explain how this occurs.
(N/A) The Tyndall effect is the scattering of light by particles in a colloid or a very fine suspension. In a dense forest, the air contains mist, which consists of tiny water droplets suspended in the air. These water droplets act as colloidal particles. When sunlight enters the forest through the canopy, these tiny droplets scatter the light, making the path of the light beam visible. This phenomenon is known as the Tyndall effect.
