Why do the component colours of incident white light split into a spectrum while passing through a glass prism, explain
Advertisements
उत्तर
The splitting of a beam of white light into its seven constituent colours, when it passes through a glass prism, is called the dispersion of light.
When a beam of white light enters a prism, it gets refracted and splits into its seven constituent colours, viz. violet, indigo, blue, green, yellow, orange, and red. This splitting of the light ray occurs because of the different angles of bending for each colour. Hence, each colour while passing through the prism bends at different angles with respect to the incident beam. This gives rise to the formation of the colour spectrum.
