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°.
The reason that the rainbow is circular is that this is the only shape that reflects the light back to your eyes at 42Â° (or 53Â°) - water droplets below and above (or to the left and right) of the rainbow do not reflect the light to your eyes. What this means is that everyone sees a different rainbow.
