This extremely rare phenomenon of lightning striking through a double rainbow occurred in the sky over the United States, Livescience reported.
From a new photo posted on the science website Livescience, the simultaneous presence of a double rainbow and lightning created an amazing sight in the sky over Badlands National Park in South Dakota, USA.

Lightning is an electrical discharge in the atmosphere between clouds and the ground or between oppositely charged clouds. Lightning sometimes forms during sandstorms or volcanic eruptions. In the atmosphere, lightning can travel at speeds of up to 36,000 km/h and reach temperatures of up to 30,000 degrees Celsius.
Meanwhile, a rainbow is the dispersion of sunlight when it interacts with water particles in the air. When light is both reflected and refracted through water particles, it will separate into colors in the following order: red, orange, yellow, green, blue, indigo, violet. Depending on the number of times the light is reflected, scientists divide them into first, second, third, and fourth order rainbows.

Because it reflects only once, the primary rainbow has the greatest brightness. That’s why people often see primary rainbows. Occasionally, we see secondary rainbows. The order of colors in a secondary rainbow is reversed compared to the primary rainbow, with red on the inside, violet on the outside… and the brightness is weaker.

Double rainbows usually occur when two rain showers occur at the same time, that is, when water droplets combine together. When this happens, the raindrops will be of different sizes and create slightly distorted rainbows. These rainbows combine to form a twin rainbow.
In reality, twin rainbows are extremely rare. They are two rainbows that share a common origin but are separated into two separate arcs, rather than concentric circles like a double rainbow. Therefore, the order of the colors is not reversed.
