A rare five-fold rainbow shot by photographers in New Jersey.

John Entwistle captured this gorgeous rainbow while shooting a sunset in New Jersey. When John Entwistle was filming the sunset in New Jersey recently, photographer John Entwistle saw another beautiful sight: the sky was depicted as five rainbows. "I may be wrong, but it's like five times the rainbow at sunset on the Jersey Shore in New Jersey tonight. Entwistle wrote on Instagram on September 18:

This extra rainbow consists of the brightest and most vivid main rainbow and at least two other rainbows that are not too bright. Among the rainbows photographed by Entwistle, you can see five other rainbows. [Strange and Shining: Mysterious Gallery]

Generally speaking, redundant numbers are common. Gunther, a retired climate scientist at the Royal Dutch Meteorological Institute? Cohen told Life Science magazine in an email: "There are many photos of two or three superfluous molecules here." However, the five super numbers that appear in nature are abnormal.

Once again, I photographed a rainbow with a ratio of 5 1. (John Entwistle) Li Huimin, a research professor at the United States Naval Academy in Annapolis, Maryland, agrees: "Extra rainbows are actually quite common. Although their names sound redundant, they are an inherent part of any rainbow. " Even so, he added, it is challenging to see these rainbows because they are not as bright as the main rainbow, and they are often covered by the bright colors of the main rainbow. The two rainbows are formed in almost the same way, except for one difference: when sunlight enters water droplets with a density greater than that of the surrounding air, the main rainbow will be formed, and the water droplets will bend or refract the light. Once inside the water drop, the light will be reflected by the back of the water drop, and then refracted when it leaves. Because different wavelengths of light bend differently, this process occurs in many tiny droplets, and you will get a rainbow.

According to Li, the extra rainbow is formed because light waves interfere with each other along slightly different paths in raindrops. When the size of raindrops is relatively uniform, these extra particles are easier to see; This is because the paired rays passing through raindrops are more likely to be in phase and produce colored light. For droplets of different sizes, light waves are more likely to cancel each other out, which means there is no light and no extra molecules. Appear in this situation.

The redundant molecules are conical because their spacing near the horizon is smaller than that near the top of the rainbow. Cohen said: "This photo is obviously the case.

If you haven't seen it in real life, look at the photos so that you know what you are looking for. "However, just like owning a new car, once you realize the existence of supramolecules, you will start to see them in many different rainbows," Li pointed out that KDSP and KDSP were first published in Life Science magazine.
