Answer: The correct answer is Tyndall effect.
Explanation:
Colloids are defined as the mixtures where the size of the particle is within the range of 2nm to 1000 nm. In these mixtures, physical boundary is seen between the dispersed phase and dispersed medium.
Tyndall effect is defined as the effect in which scattering of light takes place by the particles present in a colloid or in very fine suspension.
For Example: Scattering of sunlight by clouds
Thus, the correct answer is Tyndall effect.
