Breaking up of the component colours of light is called dispersion. Dispersion is caused due to difference in velocity of each colour through a medium. Scattering of light takes place due to interaction of light and particles suspended in a medium. Rainbow is an example of dispersion. Blue colour of sky, red colour of sky at sunrise or sunset is example of scattering of light.
