Question

An electromagnetic radiation of frequency n, wavelength λ, travelling with velocity v in air, enters a glass slab of refractive index μ. The frequency, wavelength and velocity of light in the glass slab will be respectively
  1. nμ,λμ and vμ
  2. n,λμ and vμ
  3. n,λ and vμ
  4. nμ,λμ and v

A
n,λμ and vμ
B
nμ,λμ and v
C
nμ,λμ and vμ
D
n,λ and vμ
Solution
Verified by Toppr

Refraction at a plane surface:
μv=constant and μλ=constant
where, μ is the refractive index, v is the velocity, λ is the wavelength.
Hence, the answer is n,λμandvμ
