Refraction, Glass Slab & Apparent Depth

Let the speed of light and the polarising angle for a given medium be ' $V$ ' and ' $i_p$ ' respectively. The relation between them is: ( $C =$ speed of light in vacuum)

Show answer and solution

Answer: (d)

Brewster's law: $\tan i_p = \mu$ .
Also $\mu = \dfrac{C}{V}$ , so $\dfrac{\sin i_p}{\cos i_p} = \dfrac{C}{V}$ .
Cross-multiply: $V\sin i_p = C\cos i_p$ .
So the answer is (d).
