The splitting of white light into seven colours on passing through a transparent medium like a glass prism is called dispersion of light.
Formation of rainbow:
The raindrops act like small prisms. When sunlight enters and leaves these raindrops, the various coloured rays in white light are refracted by different amounts due to which an arc of seven colours called rainbow is formed.
