1. This breaking of light into its seven constituents is known as Dispersion. Rainbow is an example
2. A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
3.These refracted rays are the ones that you see as a rainbow. Thus, when the white light from the sun hits a raindropthe light is dispersed as it enters (like in the prism). The different colors undergo refraction and reflection due to the change of index of refraction between the water and the air.
