A double rainbow, a miracle of nature
When we observe and see a rainbow, we cannot imagine whether it is located near or far, in fact the rainbow is not actually located in any specific place. The appearance of a rainbow mainly depends on where we observe and it depends on the direction of light.
Basically, you could say that the rainbow is an optical illusion.
Rainbows represent a spectrum of seven different colors that follow each other in a specific order, namely red, orange, yellow, green, blue, indigo, and purple. The outer edge of the rainbow is red and the inner edge is purple.
Rainbow essentially occurs when white light enters a water droplet and bends in several different directions. These bent light waves are reflected from the droplet, and because the white light is separated from water, refracted light appears in the human eye as separate colors.
The double rainbow is visible above the main rainbow, the second rainbow is less bright than the first. This phenomenon occurs with double reflection, and thus causes the rotation of the color order of the second rainbow.
