The Tyndall effect, also known as Willis–Tyndall scattering, is light scattering by particles in a colloid or in a very fine suspension. It is named after the 19th-century physicist John Tyndall

The smal sized collodial particles in air can easily scatter a beam of visible light. This scattering of beam of light is called as tyndall effect.
Example - 1. Sunlight passing through canopy of dense forest.
As, in the forest, mist contains tiny droplets of water, which acts as particles of colloid dispersed in air.
2.A fine beam of light entering a room through small hole.
In here, dust and smoke pesent in air scatters the beam of light.
hope it'll help you :)
