What is Tyndall Effect and what are it's effects?

Expert Answer:

The Tyndall effect is an effect of light scattering by colloidal particles or particles in suspension.Colloidal particles are much larger than atoms or molecules. It follows from scattering theory that Tyndall scattering (by colloidal particles) is much more intense than Rayleigh scattering (by atoms or molecules). Tyndall scattering can be used to determine the size of colloidal particles.

The Tyndall Effect is caused by reflection of light by very small particles in suspension in a trasnparent medium. It is often seen from the dust in the air when sunlight comes in through a window, or comes down through holes in clouds. It is seen when headlight beams are visible on foggy nights
