Tyndall Effect:

Tyndall Effect or Tyndall scattering is the

John Tyndall, one of Ireland’s most influential and successful scientists, was the first person ever to explain why the sky is blue, and which colors combine to make up the rainbow. As evident here, his primary interest was the in interaction of light with matter.

This phenomenon usually carried out to check whether a given sample is a true solution or a suspension (colloid).

The Tyndall Effect

The scattering effect of light produced by colloidal particles, when a beam of light is let through a solution containing intermediate particles (1 nm to 1 μm) known as colloidal particles, is termed as Tyndall effect.

The Tyndall effect

Tyndall is observed in colloids and sometimes in mixtures, but it is never exhibited by true solutions. The reason behind this scattering effect is the suspension particles that exhibit colloidal motion (Brownian motion).

Factors affecting Tyndall Effect

The amount of light scattered depends on the intensity of incident light and the density of particles.

Applications of Tyndall’s Effect

Driving in fog
