Question

At noon the sun appears white as:

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

Answer 1

The correct option is A

light is least scattered

At noon, the sun is overhead in the sky and the light coming from the sun travels a relatively shorter distance through the atmosphere to reach the earth. In this case the blue light is not scattered much. As the light coming from the overhead sun contains almost all its constituent colours in the right proportion, the sun appears white to us at noon.
