Why is the sequence of colors in the secondary rainbow reverse of that in the primary rainbow?

(a) Refraction of light

(b) Two internal reflection

(c) Reflection of light

(d) Dispersion

This question was addressed to me by my school principal while I was bunking the class.

The doubt is from Ray Optics in portion Ray Optics and Optical Instruments of Physics – Class 12

Best answer
The correct choice is (b) Two internal reflection

To explain: The sequence of colors in the secondary rainbow is the reverse of that in the primary rainbow because a secondary rainbow is formed by two internal reflections of light in water droplets while a primary rainbow is formed by just one total internal reflection.
