What is a Tyndall effect and how does it relate to our observation when shining light through the milk-water suspensions on?
Answer (1)
The Tyndall Effect is the scattering of light as it passes through a colloid (a mixture where particles do not settle). This makes the light beam visible in the mixture.In the case of milk-water suspension:Milk has tiny fat and protein particles that scatter the light.When you shine a flashlight through the milk-water mix, you can see the path of the light because of the Tyndall Effect.This shows that the milk-water mixture is a colloid, not a true solution.Example:In clean water, light passes straight and is not visible. But in milk-water, you see the beam—this is the Tyndall Effect in action.
