Question

(i.) Why does the Sun appear reddish early in the morning? (ii) Draw a ray diagram showing the dispersion through a prism when a narrow beam of white light is incident on one of its refracting surface.

Answer 1

Explanation:

It is due to scattering of light. Light near the horizon passes thicker layers of air and larger distance of atmosphere hence, most of the blue light is scattered away and longer wavelengths reach our eyes giving rise to reddish colour of sun.
