Refraction, Glass Slab & Apparent Depth

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

Show answer and solution

Answer: (d)

  1. Brewster's law: tan⁡ip=μ\tan i_p = \mu.
  2. Also μ=CV\mu = \dfrac{C}{V}, so sin⁡ipcos⁡ip=CV\dfrac{\sin i_p}{\cos i_p} = \dfrac{C}{V}.
  3. Cross-multiply: Vsin⁡ip=Ccos⁡ipV\sin i_p = C\cos i_p.
  4. So the answer is (d).
