From leprechauns to unicorns to Dorothy to Kermit the Frog, pop culture is full of references to characters that are looking for something “over the rainbow” or “at the rainbow’s end” or whatever. However, what you and I perceive as a rainbow is really a bit of an illusion–there’s no way to find the “end of the rainbow” because the rainbow isn’t really there. On today’s episode of Weather Break, Dr. Jon Schrage tries to explain how rainbows work and why it’s impossible to find “the end of the rainbow”.
It’s surprisingly hard to find good information online about rainbows. We’re pretty happy with what we found at UCAR, How Stuff Works, and WebExhibits, but if you know of a better source of information, please let us know!
