Question

When white light enters a prism, it gets split into its constituent colours. This is due to:

• A. High density of prism material
• B. Value of $\mu$ is different for different $\lambda$
• C. Diffraction of light
• D. Velocity changes for different frequencies

Answer 1

The correct option is B Value of $\mu$ is different for different $\lambda$

When white light enters a prism, is gets split into its constituent colours. This is due to value of $\mu$ being different for different colours of light as they differ in wavelengths.
