SATHEE: Optics Question 720

Optics Question 720

Question: The length of the optical path of two media in contact of length $d_{1}$ and $d_{2}$ of refractive indices $

{\mu _{1}} $a n d$ {\mu _{2}} $ respectively, is

Options:

A) $μ_{1} d_{1} + μ_{2} d_{2}$

B) $μ_{1} d_{2} + μ_{2} d_{1}$

C) $\frac{d_{1} d_{2}}{μ_{1} μ_{2}}$

D) $\frac{d_{1} + d_{2}}{μ_{1} μ_{2}}$

Show Answer

Answer:

Correct Answer: A

Solution:

Optical path = $μ t$ In medium (1), optical path = $μ_{1} d_{1}$ In medium (2), optical path = $μ_{2} d_{2}$

$∴$ Total path = $μ_{1} d_{1} + μ_{2} d_{2}$
