For example, if the Sun is overhead, any possible rainbow appears near an observer's feet ...
Rainbows appear when sunlight is reflected by raindrops, similar to a prism. However, when the raindrops reflect the light two times, it creates a dimmer second rainbow, a rare event known as a ...

In secondary rainbows, that order is reversed with violet coming first from top to bottom. A secondary rainbow is much fainter than a primary one because the intensity of light is reduced.

It takes all the colors of the rainbow for us to see it that way. It happens because of something called the Rayleigh effect, or Rayleigh scattering, named after a British scientist who first ...
