What is Tyndall Effect and example in our life ?

We all have seen ribbons of light peeking through window in the morning .This is just an example of Tyndall Effect.

What is Tyndall Effect?

This effect refers to scattering of light when it passes through a colloid system composed of smaller particles. One more example for this is ----

We have 2 jars of water . One jar contains pure water and other one contains water with impurities or particles. Now we will pass a beam of light through both of them..

The light passing through jar containing pure water emerges as it is , without any change . But when the light passes through the jar containing water with impurities , then light will undergo either reflection or refraction or both.

This effect is widely used in Chemistry labs .
