Why do rainbows form? How are they formed?
That makes sense. Is it possible to see a full circle rainbow?
Yes, a full circle rainbow can be seen from high up in the air, such as from an airplane. It's also possible to see a full circle rainbow if you're standing at the edge of a body of water such as a lake or the ocean, with the sun setting behind you and a rain shower in front of you. However, these are rare occurrences and require very specific conditions.
