Assertion: When a fine beam of sunlight enters a smoke-filled room through a small hole, the path of the light is visible  Reason: The scattering of light from the suspended particles present in air makes the path of the light visible
 

Dear Student,

As there is no option provided. Both assertion and reason are correct.

Tyndall effect can also be observed when a fine beam of light enters a room through a small hole. This happens due to the scattering of light by the particles of dust and smoke in the air. Tyndall effect is due to scattering of light by colloidal particles. The path of light beam through the colloid become visible.

Regards
