Answer Details
When white light passes through a glass prism, it gets separated into its constituent colours, forming a rainbow-like spectrum. This is because different colours of light travel at different speeds through the glass due to the phenomenon of refraction. The amount of bending of the different colours of light is different because each colour has a different wavelength and thus travels at a different speed. Therefore, the dispersion occurs due to the different speeds of the colours in the glass.
