Final answer:
The secondary rainbow appears above the primary rainbow with reversed color order, from red at the bottom to violet at the top, due to an extra reflection inside the water droplets and is fainter than the primary bow.
Step-by-step explanation:
Compared to the primary rainbow, the secondary rainbow is produced when two internal reflections occur within the water droplet. This secondary bow has an arc that is higher in the sky than the primary rainbow arc and exhibits a reverse color sequence, with red being at the lower angle and violet appearing at the higher angle from the observer's perspective. This change in color order and height of the arc with respect to the primary rainbow is due to the extra reflection inside the water drops that the light undergoes to form the secondary rainbow. The secondary rainbow is also fainter and less vibrant than the primary rainbow since more light is lost upon the second reflection.
