When sunlight hits a rain droplet, some of the light is reflected. The electromagnetic spectrum is made of light with many different wavelengths, and each is reflected at a different angle. Thus, spectrum is separated, producing a rainbow. Red has the longest wavelength of visible light, about 650 nanometers.
A rainbow is a multicolored arc made by light striking water droplets. The most familiar type rainbow, including this one in southern Chile, is produced when sunlight strikes raindrops in front of a viewer at a precise angle. The colors on a primary rainbow are always in order of their wavelength, from longest to shortest: red, orange, yellow, green, blue, and violet
