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°.
Unlike a double rainbow that consists of two separate and concentric rainbow arcs, the very rare twinned rainbow appears as two rainbow arcs that split from a single base. The colours in the second bow, rather than reversing as in a secondary rainbow, appear in the same order as the primary rainbow. A normal secondary rainbow may be present as well. Twinned rainbows can look similar to, but should not be confused with supernumerary bands.
