Question

At noon the sun appears white as

• A. light is least scattered
• B. all the colors of the white light are scattered away
• C. blue color is scattered the most
• D. red color is scattered the most

Answer 1

The correct option is A

light is least scattered

It is due to scattering of light. At noon, the sun is at the nearest point to earth. Hence light has to travel very small distance therefore resulting in least scattering. During sunrise and sunset, the sun is at the farthest position. Here blue light gets scattered off and the red light, due to its larger wavelength, can travel a longer distance and hence reach our eyes. Thus we see the sun red.
