What happens when a ray of ordinary light is passed through a triangular glass prism?
उत्तर
When a ray of ordinary light is passed through a triangular glass prism, the light splits into a spectrum of seven colours. This splitting of light into its constituent colours is called dispersion of light. The role of the prism is to separate the seven colours of the white light.
