Optics Question 952

Question: The critical angle of light going from medium A to medium B is $θ$ . The speed of light in medium A is v. The speed of light in medium B is:

Options:

A) $\frac{v}{\sin θ}$

B) $v \sin θ$

C) $v \cot θ$

D) $v \tan θ$

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $\sin θ = \frac{1}{μ} = \frac{C_{A}}{C_{B}}$

$\Rightarrow C_{B} = \frac{V}{\sin θ}$
