Question

What is Tyndall effect give two eg

Answer 1

Answer:

The Tyndall effect is light scattering by particles in a colloid or in a very fine suspension. Under the Tyndall effect, the longer wavelengths are more transmitted while the shorter wavelengths are more diffusely reflected through scattering.

Examples:

1.  When a beam of light is directed at a glass of milk, the light is scattered. This is due to the Tyndall effect.

2. The visible beam of headlights in fog is caused by the Tyndall effect. The water droplets scatter the light, making the headlight beams visible.
