Why are rainbows forming?
Rainbows are a striking and beautiful meteorological phenomenon caused by light refraction. In order to shape the rainbow, the sun must be near the horizon, and there must be heavy fog, fog or rain opposite the sun. The observer standing between the sun and the rainbow would see an arc of 180 degrees that pass through a visible spectrum from red to purple. In some cases, if the conditions are correct, double rainbows are formed, with a pale rainbow in reversed colors above the primary rainbow, and in other cases a fully circular rainbow, usually from the inner aircraft flying above the ground, was observed. The cause of the rainbow is basically a reflection of sunlight through individual drops of water. The light enters the water and reflects from the opposite pinepocles of water, jumping back over the entrance point. Because the angle or refraction of light changes when bouncing back, it filters light into different colors that are arranged red and purple mine, because red is the longest wavelength and purple is shortest.
When double rainbows are formed, the light is tinned twice, causing the fainting rainbow to reflect the primary. A triple rainbow could also form potentially, although extremely rare. Once the water has scattered sufficiently or the sun moves, the rainbow disappears because the conditions are no longer optimal for the refraction of light through the drops. It is also possible for Moonbow to be formed, although people have difficulty in color resolution in the dark, usually appear in white and gray shades.
People looking for rainbows should go out when the service is near the horizon and there was a heavy rain or an active storm occurred. If the observer turns his back to the sun and looks in a direction that is immediately opposite the sun, it can see the rainbows, if the conditions are correct, with the peak of the arch located directly opposite the sun. In some cases, the lighting conditions are suitable for the rainbows to form in close proximity to the observer: otherwise the rainbow will continue to look as if the pursuerE pushed until they finally disappear completely because the observer actually passed.
