Question

A prism splits a beam of white light into its constituent colours. This is so because .......... of different colours is different.

• A. energy
• B. none of these
• C. amplitude
• D. velocity

Answer 1

Answer: (D)

A prism splits a beam of white light into its constituent colours.

because when white light pass through prism they travel different path due to change in their wavelength due to medium refractive index.

the change in wavelength alters the velocity of different colours and they deviates according to their wavelength.

Thus option A is correct.
