Q87 / 90 · JEE Main 2012 (07 May Online) · Physics

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

  • Correct answer
    A
    (i), (ii) and (iii)
  • B
    (i) and (ii)
  • C
    (i), (ii) and (iv)
  • D
    (iii) and (iv)
