Question related to Light and Rainbows

[Michael Novelo 4G]

In previous lectures the professor discussed how during a rainstorm, raindrops act as a prism and when light goes through them it displays different colors causing a rainbow. My question is why do we typically only see one rainbow and not multiple ones spread throughout the city if rain is occurring in various areas and why is it that double rainbows form in the same area sometimes?

[Ethan Breaux 2F]

Well the formation of rainbows required pretty specific stuff like there has to be rain and sun and the sunshine needs to be going through at a certain angle in respect to whoever is looking at it and obviously there has to be water droplets in the air and again no clouds. Its more common to see rainbows when it stops raining. Oh and double rainbows are made by unicorns and leprechauns and magic and they always lead to a big pot o' gold. Don't fact check that just trust me.
