Question

Sunlight has to travel distance in the atmosphere during sunrise or sunset as compared to the noon.

• A. smaller
• B. larger
• C. equal

Answer 1

The correct option is B larger

Sunlight has to travel larger distance in the atmosphere during sunrise or sunset as compared to the noon.
Thus, all the colours (smaller wavelength) from white sunlight scatter away except the red colour. Hence, the sky looks reddish during sunrise or sunset.
