Which of the following is NOT involved in the formation of secondary rainbow? (a) Refraction (b) Angular dispersion (c) Interference (d) Total internal reflection

Answer: (c). A rainbow forms by refraction at entry and exit, dispersion of colours, and internal reflection (two in the secondary bow) inside drops. Interference is not involved. So the answer is (c) interference.
