Question

Dispersion of light through a glass prism is the phenomenon of:

• A. Splitting of white light into its components due to differential speeds of various colours in air
• B. Splitting of white light into its components due to differential speeds of various colours in glass
• C. Splitting of white light into its components due to differential speeds of various colours in air as well as glass
• D. Splitting of white light into its components due to differential speeds of various colours in glass as well as shape of the prism which offers differential angular deviation to different colours
• E. Splitting of white light into its components due to differential speeds of various colours in glass as well as shape of the prism which offers same angular deviation to different colours

Answer 1

The correct option is D

Splitting of white light into its components due to differential speeds of various colours in glass as well as shape of the prism which offers differential angular deviation to different colours

Splitting of white light into its seven components on passing through a prism is called dispersion.
