Optics Question 723

Question: If $_{i} μ_{j}$ represents refractive index when a light ray goes from medium i to medium j, then the product $_{2} μ_{1} \times_{3} μ_{2} \times_{4} μ_{3}$ is equal to

[CBSE PMT 1990]

Options:

A) $_{3} μ_{1}$

B) $_{3} μ_{2}$

C) $\frac{1}{_{1} μ_{4}}$

D) $_{4} μ_{2}$

Show Answer

Answer:

Correct Answer: C

Solution:

$_{2} μ_{1} \times_{3} μ_{2} \times_{4} μ_{3} = \frac{μ_{1}}{μ_{2}} \times \frac{μ_{2}}{μ_{3}} \times \frac{μ_{3}}{μ_{4}} = \frac{μ_{1}}{μ_{4}} =_{4} μ_{1} = \frac{1}{_{1} μ_{4}}$
