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



The sun and the sky appear to have yellow and blue colors respectively because Earth’s atmosphere scatters the colours of the white light. 

The colours we see are the ones left after the scattering. The phenomenon is called Rayleigh Scattering. 

  • When it is noon, the sun is at its peak in the sky, and has to travel the least distance .
  • The light is least scattered and retains almost all it’s colours , making the sun appear white.


So, the correct answer is (a)

  1. Class 10
  2. Chapter 11 Class 10 - Human Eye and Colourful World (Term 1)
