Question

write about tyndall effect​

Answer 1

☢️The Tyndall effect is light scattering by particles in a colloid or in a very fine suspension.

Answer 2

$\huge{\bold{ANSWER:-}}$

The scattering of light by the colloidal particles is known as Tyndal effect.

Tyndal effect is observed only when the following two conditions are satisfied.

(a) The diameter of the dispersed particles is not much smaller than the wave length of the light used.

(b) The refractive indices of the dispersed phase and the dispersion medium must differ greatly in magnitude.

Examples:-

• Blue colour of sky and sea water.
• Visibility of tails of comets.
• Twinkling of stars.
