In the following picture, you can see the faint secondary bow in the upper right. This secondary rainbow results from two internal reflections (instead of one) inside the raindrop, leading to the colors appearing in the opposite order as the primary bow. Sometimes, a second, fainter rainbow can be seen in the sky. This process happens to an assortment of raindrops falling from the sky leading to the existence of many rainbows at the same time however, which one you see (and how much of one you see) depends on your viewpoint relative to the angle of the sun above the horizon behind you. This refracted light hits the back of the raindrop, is reflected internally within the drop, then is bent (refracted) once again as it exits the drop.īecause the different colors of the sunlight bends at different angles, the result of one internal reflection means the primary rainbow will have red on the outside and blue on the inside. When the sunlight encounters a raindrop, some of the light is bent as it enters the drop. In 1665 Isaac Newton, through his i nfamous prism experiment, was able to prove that the white light of the sun was actually composed of a color spectrum. The sun’s visible light entered the prism and was refracted (bent) through the prism, with the red (longest wavelength) bending the least and the shorter wavelength violet bending the most.Ī raindrop falling from a cloud can act as a prism, bending and reflecting the light to produce the colors of the rainbow. Most of the sun’s energy is emitted as visible light, which includes a range of colors (ROYGBIV). How does this occur? First, consider the energy emitted by the sun, which includes waves of energy in the UV, infrared, and visible portions of the electromagnetic spectrum. Rain showers over the tropical Hawaiian Islands, and elsewhere, can lead to vibrant rainbows. To understand how these bands form, we first need to consider what creates a rainbow in the first place. “Supernumerary” means “more numerous” and is an adjective used not only for describing this optical phenomenon, but also for everything from teeth to military officers. These faint, pastel bands of light are referred to as supernumerary bows. There are actually additional colored bands bordering the bright primary rainbow in this picture from the Hawaiian Island of Oahu.
