Question

Give two examples of "tindel effect"​

Answer 1

Answer:

Examples of the Tyndall Effect

Milk is a colloid that contains globules of fat and protein. When a beam of light is directed at a glass of milk, the light is scattered. This is a great example of the Tyndall effect.

When a torch is switched on in a foggy environment, the path of the light becomes visible. In this scenario, the water droplets in the fog are responsible for the light scattering.

Opalescent glass has a bluish appearance when viewed from the side. However, orange-colored light emerges when light is shined through the glass.

Answer 2

$\mathtt{\huge{\underline{\bf{\red{Answer :-}}}}}$

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

The colloidal particles first absorb light and then a part of the absorbed light is scattered from the surface of the colloidal particles. Maximum scattered intensity is being in a plane at right angles to the plane of incident light. The path becomes visible when seen from that direction.

• It forms a bright light of cone known as a tyndall cone.

• It leads to zig zag moment of the particles of atmosphere known as brownian moment.

• The diameter of dispersed particle are not less than light wavelength.

• The disperse phase & dispersion medium is great in magnitude.
