Best Answer: The double rainbow is nothing more than light being refracted twice instead of once in a rain drop. They always do that but the second refracted ray is often so dim that we can't see it. just now. Report Abuse. Well, a double rainbow consists of a primary rainbow and a secondary one. Secondary rainbows are caused by a double reflection of sunlight inside the raindrops, and appear at an angle of 50Â°â53Â°.
When the spectrum is split into its different wavelengths then we can see colors, this is what happens when you see rainbows. Water droplets in the clouds break up sunlight into different wavelengths and then we can see a rainbow. Glass prisms (like on a chandelier) also break light into rainbows.
