Solution

The correct option is D All of these
A beam of white light or sunlight splits into a spectrum of 7 colors. This spectrum is visible due to bending of lights of different colors at different angles with respect to the incident ray through a prism. Red light bends the least whereas violet light bends the maximum. Rainbow is an example of dispersion of light through water droplets that act like a prism.
