Occasionally, we see two rainbows at the same time, known as a double rainbow. Wonder what causes this? Well, following the path of a ray of sunlight as it enters and is then reflected inside of the raindrop provides some answers to that very question.
Not all of the energy of the ray of sunlight escapes the raindrop after it is reflected one time. Actually, a part of the ray is reflected again and travels inside the raindrop to emerge..
Normal rainbows are called primary rainbows and are produced by one internal reflection. The double rainbow comes from two internal reflections, the sun rays then exit the drop at a angle of 50° instead of the 42° angle of the primary rainbow.
It is possible for light to be reflected more than twice within a raindrop, and one can calculate where the higher order rainbows might be seen; but these are never seen in normal circumstances.
Your explanation is good, but your photo is not. It is photoshopped. The outer rainbow in a real double rainbow has reversed colors.
