Question
Define Tyndall effect.
✓

Answer

The Tyndall effect is the scattering of light as a light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible. As with Rayleigh scattering, blue light is scattered more strongly than red light by the Tyndall effect.
