Dear Student,

This is occur due to Tyndal effect or scattering of light. It well describe by below:-

Scattering is the phenomenon by which a beam of light is redirected in many different directions when it interacts with a particle in the atmosphere. When sunlight strikes molecules in our atmosphere, the light is redirected in many directions. 

The blue light is scattered more than the red light causing the sky to be blue.

Red light has greater wave length than the others and hence less interacts with the particles in the atmosphere therefore scatters least. 

Regards,
