Question

The angle of incidence at which reflected light is totally polarized for reflection from air to glass (refraction index n) is.

• A. $\sin^{- 1}(n)$
• B. $\sin^{- 1}\left( \frac{1}{n} \right)$
• C. $\tan^{- 1}\left( \frac{1}{n} \right)$
• D. $\tan^{- 1}(n)$

Answer 1

Answer: (D)

$\tan^{- 1}(n)$

Answer 2

μ = tanθ_P ⇒ θ_P = tan^–1 n
