Dispersion. Visible light is actually made up of different colors. Each color bends by a different amount when refracted by glass. That's why visible light is split, or dispersed, into different colors when it passes through a lens or prism.An example of a dispersion is the colored rays of light coming from a prism which has been hung in a sunny window.

light ray of different colour travel in same speed in vacuum , and air but in another medium when it refract itt bends through different angle in different medium and different speed , this lead to diepersion of light
