What is the Tyndall effect?
Short Answer

Solution
The Tyndall effect is the scattering of light by colloidal particles when an intense beam of light passes through a colloidal solution, illuminating the path with a bluish light. It occurs because the colloidal particles are comparable in size to the wavelength of visible light, causing the light to scatter. This effect helps distinguish colloids from true solutions, which do not show scattering due to the smaller size of their particles.
