Which of the following processes play a part in the formation of a rainbow? (i) Refraction (ii) Total internal reflection (iii) Dispersion (iv) Interference

Options

  1. A(i), (ii) and (iii)
  2. B(i) and (ii)
  3. C(i), (ii) and (iv)
  4. D(iii) and (iv)

Correct answer

A. (i), (ii) and (iii)

Step-by-step solution

Rainbow is formed due to the dispersion of light suffering refraction and total internal reflection (TIR) in the droplets present in the atmosphere.
