Question: How are rainbows made?

Jose Brandao-Neto answered on 15 Nov 2019:

rainbows are a result of refraction of sun light passing through rain.

PRACTICALITIES: to see a rainbow move your head so the sun is behind you and look forward. If there’s rain falling in that area, you’ll see a rainbow.

Did you know there is an icycle (small pieces of ice) version of the rainbow? it’s called sundog and you can see one if you look towards the sun and there are icycles in the air in that area. they are *really* impressive as well. Check that:
