Question

what is disperson of light? what is it's cause​

Answer 1

Cause of dispersion of light: When light passes through a prism, the different frequencies of light travel at different velocities. Because of refraction, the different velocities make the angles of refraction different, causing the light to travel in slightly different directions.
