What is the Tyndall effect?

The Tyndall effect is an optical scattering or scattering effect of light caused by particles of a colloidal scattering. This means that dust particles, for example suspended in the air, can be visible through a beam of light through the trees.

This phenomenon was first observed by Michael Faraday in 1857. The effect was later studied by English physicist John Tyndall.

Through this phenomenon it is also possible to see the water droplets that form the fog through the car's headlight. Also the light beam of a flashlight by means of a container containing gelatin.
