Rainbows are formed when sunlight is scattered from raindrops into the eyes of an observer. Most raindrops are spherical rather than the often depicted 'teardrop' shape and it is this spherical shape that provides the conditions for a rainbow to be seen. The position of the sun and the raindrops in relation to the observer need to be just right ...A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors. When light exits the droplet, it makes a rainbow. Rainbow at Suuroy, Faroese Islands.Rainbow Symphony is the top source online for diffraction grating slides and optical tools.
