8.B
Explanation:
If white light is passed through a prism (a triangular block of glass), then the light splits up into colours of the rainbow: This is because white light is, in fact, a combination of these colours. The spectrum of the different colours or wavelengths of light has been produced on the screen.
Refraction is the bending of the path of a light wave as it passes from one material into another material. The refraction occurs at the boundary and is caused by a change in the speed of the light wave upon crossing the boundary.
