What is Tindall effect?

Tyndall Effect is one of the important phenomenon of physics. It refers to scattering of light. Whenever a beam of light passes through a colloidal solution, the colloidal particles do not allow the same light to pass away. Then, this light ray collides with the colloidal particles of colloidal solution and gets scattered. This is known as Tyndall effect. Due to this phenomena, the path of light rays become visible. It is responsible of blue color of sky, reddish color of sun and many more.
