Optics Question 776

Question: The wavelength of light in air and some other medium are respectively $λ_{a}$ and $λ_{m} .$ The refractive index of medium is

[RPMT 2003]

Options:

A) $λ_{a} / λ_{m}$

B) $λ_{m} / λ_{a}$

C) $λ_{a} \times λ_{m}$

D) None of these

Show Answer

Answer:

Correct Answer: A

Solution:

$μ_{m} = \frac{c}{v} = \frac{n λ_{a}}{n λ_{m}}$

$= \frac{λ_{a}}{λ_{m}}$
