POOJA KOTHARIMom of a 8 yr 5 m old boy4 years agoA. A rainbow has seven colors because water droplets in the atmosphere break sunlight into seven colors. A prism similarly divides light into seven colors. When light leaves one medium and enters another, the light changes its propagation direction and bends. This is called refraction.
