Explain what is observed When a beam of light is passed through a colloidal sol.
When a beam of light is passed through a colloidal solution, then scattering of light is observed. This is known as the Tyndall effect. This scattering of light illuminates the path of the beam in the colloidal solution.
Scattering of light by the colloidal particles takes place and the path of light becomes visible (Tyndall effect)
