Light is incident on a glass plate of refractive index 1.55 The reflected and refracted ray at right angles to each other. The ratio of wavelengths of reflected and refracted light is

Answer: (B)

Solution

Reflected light stays in air (wavelength λ) and refracted light has wavelength λ/μ, so the ratio λ_reflected/λ_refracted = μ =
