What Causes a ‘Rainbow’ and Why Do They Appear in Different Places?

A rainbow is like a magical paintbrush in the sky that paints colorful arcs. It happens when sunlight bounces inside water droplets, and each color of light bends at a slightly different angle, just like how a prism splits white light into colors. You see it only when the sun is behind you and rain is in front. Sometimes it appears as a full circle, but most of the time, we only see part of it because the ground blocks the rest.
