The Tyndall effect is the scattering of light by tiny particles in a colloid or a very fine suspension.

In Simple Words we can say that when a beam of light passes through a mixture, and the light scatters due to small particles in it, this is called the Tyndall effect.

These particles are small enough to stay suspended, but large enough to scatter light. As a result, the path of the light becomes visible.

We can observe the Tyndall effect in fog, mist, or a dusty room when sunlight or a beam of light passes through. It helps us identify colloidal mixtures, because true solutions do not show this effect.
