In a rainbow, why is the top colour red and violet on bottom even though red emerges farther (42 degrees) than violet (40) when seen in a single drop?

Question

I don't understand this image or why primary rainbow has red at the top even though in a single drop red is deviated most.

Answer 1

You only see the color that aims at you. From the higher drops that is red. From the lower drops that is violet.
