Solution
Tyndall Effect:
It is the effect under which a ray of light scatters in all directions as soon as it encounters a colloidal or suspension particle. It is shown by colloidal particles because the colloidal particle size is roughly equal to the wavelength of the light.
Four instances of observing the Tyndall effect:
- It can be observed in the fog.
- It can be observed when light passes through the canopy in the forest.
- It is the reason for the blue color of the sky.
- It can be observed when light passes through the milk.
