Q: Why do we only see one rainbow at a time?

Q: Why do we only see one rainbow at a time?

The next time you see a rainbow, draw an imaginary line from the sun through you. You’ll notice that this line goes exactly through the middle of the rainbow. This happens again at around 52°, but this time the effect is caused by two reflections inside the water drop. As a result of there being two reflection (instead of one), the colors in secondary rainbows are reversed compared to the primary rainbow at 42°. Entirely unimportant fun fact: the only way to see a complete, full circle, rainbow is to be flying (or falling).
