Appreciate the people who always set their camera to record and snap beautiful scenes of the environment since they do a great job for the rest of the world. These are the blessings of technology. You’ll be able to record awesome natural phenomena although you aren’t in the place physically.

Amanda Curtis who is a commuter in Long Island in New York captured a stunning image of a quadruple rainbow or a double-double rainbow which decorated the sky of New York in 2015. The image was amazing and it went viral all over the social media platforms. Some said that it was photoshopped.

The meteorologists acted to clear up the confusion of the people as quadruple rainbows are possible though rare. According to the meteorologists the rainbow which was captured by Amanda Curtis was technically two double rainbows. Well, these are the rainbows which are formed when the beams of the sun are reflected by droplets of water hanging in the air for a second time.

It isn’t a magic at all

You’ll be able to see two conspicuous arcs and two fainter arcs if you have a closer look at the image. The two conspicuous arcs are the primary and secondary arcs while the other fainted arcs are the ones which are made after the second reflection.

Curtis too hadn’t seen the four distinct rainbow arcs at the beginning. But yet the photo is one of the most alluring representations of colours, hope and life.

As per the descriptions of Paul Neiman, a research meteorologist at NOAA’s Earth System Research Observatory, there is a need for a large body of tranquil water to observe such doubly reflected arcs. Perhaps the large body of water may be the Hempstead Bay or the Oyster Bay as Curtis was in Glen Cove at the moment.

“For the much rarer reflected-light rainbows shown in this spectacular photo, a large glassy-smooth water surface is required behind the observer,” Neiman wrote in a lengthy but thorough Facebook explanation.

“This smooth water surface reflects the sun, such that a second solar light source is generated. This reflected sun, which is located the same number of arc degrees below the horizon as the real sun is above the horizon, creates a second primary and secondary rainbow on the opposite side of the sky from the sun, but with the center of these reflected-light rainbows above the horizon. The geometry dictates that the regular and reflected-light rainbows will join at the horizon, as this photo shows.”

The real triple or quadruple rainbows occur when the already reflected sunlight gets reflected once again or more. In a quaternary or tertiary rainbow, the arcs become fainter as the amount of sunlight gets reduced when reflected. According to the scientists, there haven’t been a verified scene of actual triple or quadruple rainbows since the past 250 years.

The quadruple rainbows can occur under the strictly perfect conditions of extremely bright sunlight and heavy rain, which are quite hard incidents to happen together. “You need a fortuitous small hole in the clouds combined with torrential rain,” stated meteorologist Raymond Lee to National Geographic.
