What is Tyndall effect?

Hi Roy, The Tyndall effect, also known as Tyndall scattering, is light scattering by particles in a colloid or else particles in a very fine suspension. It is named after the 19th-century physicist John Tyndall. It is similar to Rayleigh scattering, in that the intensity of the scattered light depe

You can put a colloidal solution in a dark room, and then pass a beam of light though it. Then, you will see path of light becomes visible with blush light. This phenomenon is called Tyndall effect.

The visible scattering of light along the path of a beam caused by discontinuities such as suspended particles.

When a beam of light is passing through a colloidal, it scattered in all direction, this phenomenon is Tyndall effect.
