The Sun appears reddish during sunrise and sunset. The phenomenon in optics which is responsible for this appearance of the Sun is

Options

  1. AReflection
  2. BTotal internal reflection
  3. CScattering
  4. DInterference

Correct answer

C. Scattering

Step-by-step solution

It is due to scattering of light. During sunrise and sunset, the sun is at the longest position. Here blue light gets scattered off and due to larger wavelength of the red light it can travel a longer distance and hence reach our eyes. This we see the sun red. But at noon, the sun is at the nearest point to earth. Hence all the colors get scattered almost equally and this you see white light.
