Which of the following statement is correct?

Asked in JEE Main 25th July 1st Shift 2022 · Dispersion and scattering

Answer: (1) In primary rainbow, observer sees red colour on the top and violet on the bottom.

Step-by-step solution

Primary rainbow: one internal reflection inside each drop.

Red leaves at about 42° from the antisolar direction, violet at about 40°, so red is on the outside (top).

The secondary bow has two reflections, reversed colours and is fainter.
