Explanation:

A secondary rainbow appears outside of a primary rainbow and develops when light entering a raindrop undergoes two internal reflections instead of just one (as is the case with a primary rainbow).
The intensity of light is reduced even further by the second reflection, so secondary rainbows are not as bright as primary rainbows.
