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°.
No. In fact, total internal reflection of sunlight is impossible inside a spherical raindrop. Rainbows are caused by the combined effects of refraction and (not total) int â¦ ernal reflection, which concentrates the light near deflection angles of 40 to 42 degrees.hen two colors reflection occur inside a raindrop at such angle that it results into secondary rainbow. When weaker light that start emerging to produce a dimmer rainbow effect.   Refraction happens as light enters and leaves a prism. Red light is refracted the least and violet light is refracted the most.
