Dispersion of Light' can be defined as the splitting of white light when it passes through a glass prism into its constituent spectrum of colors (i.e. violet, indigo, blue, green, yellow, orange and red). ... The white light splits into its constituent colors at various frequencies and various angles.

Dispersion of white light by a glass prism
When white light is made to pass through a prism, a spectrum of seven colors is formed which shows that white light is a mixture of seven different colors. Prism only acts as a medium for the separation of the seven colors. When light falls on the glass prism, refraction takes place. Since the wavelength of different components of light is different and the frequency is constant, each component gets deviated by a different angle due to the difference in velocity in the glass medium. The red color having the maximum wavelength deviates the least and forms the upper part of the spectrum whereas violet having the least wavelength deviates the most.
