Question

Scattering of light causes the blue colour of sky and reddening of the Sun at the times of sunrise and sunset.

• A. True
• B. False

Answer 1

The correct option is A

True

This is true. Scattering of light causes the blue colour of sky and reddening of the Sun at the times of sunrise and sunset. A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
