The Correct Option is D
Solution and Explanation
When white light passes through a glass prism, it splits into its seven constituent colours (VIBGYOR). This happens because different colours of light bend by different amounts when they pass through the prism due to differences in their wavelengths. This splitting of light into its colours is called dispersion. Newton’s prism experiment is the classic demonstration of dispersion of light.
