What is a Moonbow?
A rainbow is produced when sunlight is refracted by water droplets in the atmosphere, but what happens if water droplets reflect and refract moonlight? We get a moonbow.
Moonbows are much fainter than rainbows because of the lower intensity of moonlight (which is of course, reflected sunlight), and their colours are too faint to be perceived by the human eye. They appear a ghostly white. However, the colours can be seen through photography.
