In a primary rainbow, the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it. In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, with red on the inner side of the arc. This is caused by the light being reflected twice on the inside of the droplet before leaving it. Thus, a rainbow is not an object and cannot be physically approached. Rainbows span a continuous spectrum of colours. Any distinct bands perceived are an artefact of human colour vision, and no banding of any type is seen in a black-and-white photo of a rainbow, only a smooth gradation of intensity to a maximum, then fading towards the other side.
Rainbows can be caused by many forms of airborne water. These include not only rain, but also mist, spray, and airborne dew. Because of this, rainbows are usually seen in the western sky during the morning and in the eastern sky during the early evening. The rainbow effect is also commonly seen near waterfalls or fountains. In addition, the effect can be artificially created by dispersing water droplets into the air during a sunny day. Rarely, a moonbow, lunar rainbow or nighttime rainbow, can be seen on strongly moonlit nights.
The light leaving the rainbow is spread over a wide angle, with a maximum intensity at the angles 40. This diagram only shows the paths relevant to the rainbow. White light separates into different colours on entering the raindrop due to dispersion, causing red light to be refracted less than blue light. When sunlight encounters a raindrop, part of the light is reflected and the rest enters the raindrop. The light is refracted at the surface of the raindrop. When this light hits the back of the raindrop, some of it is reflected off the back.
When the internally reflected light reaches the surface again, once more some is internally reflected and some is refracted as it exits the drop. The light at the back of the raindrop does not undergo total internal reflection, and some light does emerge from the back. A rainbow does not exist at one particular location. It is possible to determine the perceived angle which the rainbow subtends as follows. For other uses, see Double Rainbow.
Double rainbow with Alexander’s band visible between the primary and secondary bows. Also note the pronounced supernumerary bows inside the primary bow. A secondary rainbow, at a greater angle than the primary rainbow, is often visible. The term double rainbow is used when both the primary and secondary rainbows are visible. In theory, all rainbows are double rainbows, but since the secondary bow is always fainter than the primary, it may be too weak to spot in practice. Secondary rainbows are caused by a double reflection of sunlight inside the water droplets.
The secondary rainbow is fainter than the primary because more light escapes from two reflections compared to one and because the rainbow itself is spread over a greater area of the sky. Each rainbow reflects white light inside its coloured bands, but that is “down” for the primary and “up” for the secondary. 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.
