Monochromatic light is reflected from air into a glass of refractive index

\mu

. The ratio of the wavelength of the incident and refracted waves is

View answer and explanation

Correct option: C

\mu: 1

Option C is correct because the refractive index is the ratio of the speed of light in vacuum to the speed of light in the medium, which is also the ratio of the wavelengths.
