Each wave length turns at a different ang1e. Its short wave lengths can make sharper turns around the corner than its longer wave lengths. When a sunbeam strikes a falling raindrop, it is refracted and forced to turn. But its colors arrange themselves in order according to wave lengths. The rainbow is a very complex display of refraction and reflection. Traveling through space, the assorted wave lengths b1End together as white or colorless light. Some are longer and some shorter than others. Its Energy pulses along in wave lengths somewhat like the crests and troughs of ocean waves. Sunlight fans out from the sun, traveling in straight lines at about 186,000 miles a second. It is created in an orderly fashion, and it behaves according to orderly rules. Light is a form of electromagnetic Energy. The raindrops do this by separating and scattering the different wave lengths of light. The raindrops act as tiny glass prisms and shiny mirrors: they bend or refract the sunbeams that strike them and then reflect them to our eyes. ![]() In the opposite side of the sky a shower of raindrops must be falling from a cloud. The rainbow appears when the sun is climbing up from the East or sliding down to the west. ![]() ![]() In a second bow, the reds are at the bottom, but the one by one order of colors is the same because of the nature of light. In a single rainbow, the reds are at the top and the blues at the bottom.
