In the formation of a rainbow light from the sun on water droplets undergoes

Options

  1. Adispersion only
  2. Bonly total internal reflection
  3. Cdispersion and total internal reflection
  4. DNone of the above

Correct answer

C. dispersion and total internal reflection

Step-by-step solution

Rainbow occurs in the form of concentric colourd circular arcs in the sky, when the sun shines on rain drops during or after the shower. This phenomenon occurs due to combined effect of dispersion, refraction and total internal reflection of sunlight by spherical drop of water.
