A secondary rainbow, at a greater angle than the primary rainbow, is often visible. The term double rainbow is used when both the primary and secondary rainbows are visible. In theory, all rainbows are double rainbows, but since the secondary bow is always fainter than the primary, it may be too weak to spot in practice.
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 ...
Common optical phenomena are often due to the interaction of light from the Sun or Moon with the atmosphere, clouds, water, dust, and other particulates. One common example is the rainbow , when light from the Sun is reflected and refracted by water droplets.
Pictures of them adorn buildings, the sides of public buses and appear on standard vehicle license plates. University of Hawaii sports teams are even named after rainbows. “For me, rainbows really signify hope and new beginnings,” said Liane Usher, the president of the Children's Discovery Center in Honolulu, which features rainbows on its ...
A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).
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.
