  • B
    In primary rainbow, observer sees violet colour on the top and red on the bottom
  • C
     In primary rainbow, light wave suffers total internal reflection twice before coming out of water drops
  • D
    Primary rainbow is less bright than secondary rainbow.
✓

Answer

Correct option: A.
In primary rainbow, observer sees red colour on the top and violet on the bottom
a
In primary rainbow, red colour is at top and violet is at bottom.

Intensity of secondary rainbow is less in comparison to primary rainbow.
