Expert Answer

The Tyndall effect is scattering of light by particles in a colloid or particles in a fine suspension. It can be seen when the light passes through the colloids or turbid substances causing the light to scatter in multiple directions. Examples are:

A blue iris in an eye is due to Tyndall scattering in a turbid layer in the iris.
The Tyndall effect in opalescentglass: It appears blue from the side, but orange light shines through.
Light being shined through milk. As milk is a collloid.
On a day when the sky is overcast, the sunlight passes through the turbid layer of the clouds, resulting in scattered, diffuse light on the ground.
Fog because it is a colloidal substance. When light hits a substance with scattered particles, it collides with the particles, causing the light to scatter in multiple directions.
The tyndall effect can be observed when the sunlight passes through the canopy of a dense forest.
This effect can also be seen when the sun sets as the sky changes color depending on how low the sun is and as a result how much atmosphere the sun's light must pass through.
The blue colour of smoke coming out from a 2 stroke engine, or even a four stroke engine where the burnt engine oil provides the particles.
The Tyndall Effect is also the reason why the sky blue.
