Tyndall effect shown by colloidal particles because of scattering of light.

Four instances of observing the Tyndall effect are:

• When a fine beam of light enters a smoke-filled dark room through a small hole.

• When sunlight passes through a canopy of dense forest in foggy/ misty conditions.

• Blue colour of sky.

• Red colour of the sun during sunrise or sunset
