Tyndall effect

1. Tyndall effect
a. Definition
British physicists, John Tyndall succeeded in studying colloids and he found a phenomenon called the Tyndall effect. Tyndall effect is the scattering of light by colloidal particles in its path. The Tyndall Effect is caused by reflection of light by very small particles in suspension in a transparent medium.

b. The implementation in daily live
The example in daily live are:
1. The dust in the air when sunlight comes in through a window, or comes down through holes in clouds
2. The light of car in the foggy condition.
The Tyndall effect is different for every light that have different wave length. For example is the yellow light is little scattering, and it’s the reason why the lamp color of car is yellow. This color can penetrate in the foggy condition.
