Light Scattering

Why does scattering of light occur?

• Light rays are reflected by atmospheric molecules and scatter in all directions

• Light rays are blocked and refracted to all directions by the clouds or particles in the air

• Light rays are transmitted and refracted in all directions by the clouds or particles in the air

The clear sky appears blue because

• blue light gets absorbed in the atmosphere.

• ultraviolet radiations are absorbed in the atmosphere.

• violet and blue lights get scattered more than lights of all other colours by the atmosphere.

• light of all other colours is scattered more than the violet and blue colour lights by the atmosphere.

These are examples of phenomenon of scattering of light except

• Sky appears blue at midday

• Sky appears reddish in the sunset

• Rainbow after rain
