Answer 2

Scattering of light explains (a) blue colour of sky.

What is the scattering of light?

• Due to large dust particles, air molecules in the surrounding and atmosphere, various wavelengths of radiation undergoes scattering.
• Since the diameter of particles is bigger than the wavelength of rays, so the rays get scattered while propagation.
• Blue colour scatters the most and so the colour of the sky is blue.

Twinkling of stars and advanced sunrise and delayed sunsets are because of the refraction phenomenon of light according to which, light bends while travelling through mediums of different densities.
