Question

When white light enters a prism, its gets split into its
constituent colours. This is due to
(a) high density of prism material
(b) because μ is different for different wavelength
(c) diffraction of light
(d) velocity changes for different frequency

Answer 1

Answer:

option b

different colours have different wavelengths and refractive index(measure of bending light) is different for diff.wavelength.

so, each colour will bend according to it's refractive index..
