Solution and Explanation
Definition: The Tyndall effect is the scattering of light by colloidal particles in its path, making the light beam visible.
Examples:
1. Sunlight passing through a forest and appearing as visible beams due to dust and water droplets.
2. A beam of light entering a dark room through a small hole appears visible due to dust particles scattering the light.
Reason: Colloidal particles or dust particles are large enough to scatter the light in all directions, making the path of the light visible.
