What is a double rainbow?
Double, as clear in the name, is a combination of two rainbows that occur at the same time in the Sky. This phenomenon commonly occurs in the morning or at sunset when the sun is low in the sky.
A rainbow usually contains seven colors: violet, indigo, blue, green, yellow, orange, and red. These colors are also known as the colors of light. A double rainbow is nothing more than a pair of two rainbows in a row with the same colors and shape.
However, the brightness of colors of both rainbows can differ mostly. The second rainbow could be lighter than the primary rainbow because more light escaped from two reflections than from one.
How does a double rainbow occur?
Double rainbows are rare beauties that mainly happen for natural reasons. It occurs when sunlight is reflected twice within a raindrop, with the red light that reaches your eye coming from the lower raindrops and the violet light from higher raindrops.
In simple terms, the secondary rainbow has different colors than the main rainbow, and it usually appears slightly higher in the sky, about 10 degrees above the primary rainbow. So, instead of the normal order of colors in a secondary rainbow, they are in reverse order.
