Because each person's horizon is a little different, no one actually sees a full rainbow from the ground.
In fact, no one sees the same rainbow—each person has a different antisolar point, each person has a different horizon. Someone who appears below or near the "end" of a rainbow to one viewer will see another rainbow, extending from his or her own horizon. A rainbow shows up as a spectrum of light: a band of familiar colors that include red, orange, yellow, green, blue, and violet.
The name " Roy G. Biv " is an easy way to remember the colors of the rainbow, and the order in which they appear: red, orange, yellow, green, blue, indigo, and violet.
Many scientists, however, think " indigo " is too close to blue to be truly distinguishable. White light is how our eyes perceive all the colors of the rainbow mixed together.
Sunlight appears white. When sunlight hits a rain droplet, some of the light is reflected. The electromagnetic spectrum is made of light with many different wavelength s, and each is reflected at a different angle. Thus, spectrum is separated, producing a rainbow.
Red has the longest wavelength of visible light, about nanometer s. It usually appears on the outer part of a rainbow's arch. Violet has the shortest wavelength about nanometers and it usually appears on the inner arch of the rainbow.
At their edges, the colors of a rainbow actually overlap. This produces a sheen of "white" light, making the inside of a rainbow much brighter than the outside. Visible light is only part of a rainbow. Infrared radiation exists just beyond visible red light, while ultraviolet is just beyond violet. There are also radio wave s beyond infrared , x-ray s beyond ultraviolet , and gamma radiation beyond x-rays.
Scientists use an instrument called a spectrometer to study these invisible parts of the rainbow. The atmosphere opposite a rainbow, facing the sun, is often glowing.
This glow appears when rain or drizzle is falling between the viewer and the sun. The glow is formed by light passing through raindrops, not reflected by them. Some scientists call this glow a zero-order glow.
Sometimes, a viewer may see a "double rainbow. Double rainbows are caused by light being reflected twice inside the raindrop. As a result of this second reflection, the spectrum of the secondary rainbow is reversed: red is on the inner section of the arch, while violet is on the outside. Light can be reflected from many angles inside the raindrop.
A rainbow's "order" is its reflective number. Primary rainbows are first-order rainbows, while secondary rainbows are second-order rainbows. Higher-order rainbows appear to viewers facing both toward and away from the sun. A tertiary rainbow, for example, appears to a viewer facing the sun. Tertiary rainbows are third-order rainbows—the third reflection of light. Their spectrum is the same as the primary rainbow.
Tertiary rainbows are difficult to see for three main reasons. First, the viewer is looking toward the sun—the center of a tertiary rainbow is not the antisolar point, it's the sun itself. Second, tertiary rainbows are much, much fainter than primary or secondary rainbows. Finally, tertiary rainbows are much, much broader than primary and secondary rainbows.
