Question

Light scattering by colloidal particles is called Tyndall effect.

• A. True
• B. False

Answer 1

The correct option is A True

Colloid:

• It is defined as a Heterogeneous mixture in which the dispersed insoluble particles of one substance are suspended in another substance.
• The size of the Colloidal particle ranges between 1-1000 nm.

Tyndall Effect:

• The scattering of light by Colloidal particles is called the Tyndall effect.
• The path of the light beam through the colloid becomes visible when a strong beam of light is passed through a colloid kept in a dark room
• For example The sky is blue in colour due to the scattering of the blue colour of the sun's light by colloidal particles, i.e., due to the Tyndall effect.

Therefore, the given statement is True.
