rainbow
A rainbow is formed when white light (such as sunlight) passes through water droplets, ice crystals, or glass. The light rays are refracted, or bent, by different amounts depending upon their wavelength. This has the effect of spreading the white light out into a broad band of the colors making up the white light.
