Question

What is Tyndall effect? ​

Answer 1

$\green{ \underline{ \boxed{ \odot\mid{ \bf{Answer:-}}}}}$

⟶The Tyndall effect is the phenomenon in which the particles in a colloid scatter the beams of light that are directed at them. This effect is exhibited by all colloidal solutions and some very fine suspensions. Therefore, it can be used to verify if a given solution is a colloid. The intensity of scattered light depends on the density of the colloidal particles as well as the frequency of the incident light.

Answer 2

The Tyndall effect is scattering of light by particles in a colloid or particles in a fine suspension. It can be seen when the light passes through the colloids or turbid substances causing the light to scatter in multiple directions. Examples are fog because it is a colloidal substance.
