Question

In the white light of sun, maximum scattering by the air molecules present in the earth's atmosphere is for:

• A. red colour
• B. yellow colour
• C. green colour
• D. blue colour

Answer 1

The correct option is D blue colour

Answer is D.

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.
Hence, the white light from the sun scatters more of the blue color in the spectrum.
