Question

What is tyndall effect . What is its cause. Name two phenomena observed in daily life which are based on tyndall effect?

Answer 1

Tyndall effect is due to scattering of light by the colloidal particles

Cause of Tyndall effect:

The size of the colloidal particle is relatively larger than the solute particle of a true solution.

The colloidal particles first absorb energy from the incident light and then scatter a part of this energy from their surfaces.

Thus, Tyndall effect is due to scattering of light by the colloidal particles and the colloidal particles are seen to be moving as points of light moving against a dark background.

Some daily phenomena based on Tyndall effect are as follows :  

(i) When a fine beam of sunlight enters a smoke-filled room through a small hole, the smoke particles become visible due to the scattering of light.  

(ii) When sunlight passes through a canopy of a dense forest, the tiny water droplets in the mist scatter light and become visible.
