Question

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

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

Answer 1

Answer: (D)

$\mu =tan{\theta }_P\Rightarrow {\theta }_P=ta{n}^{-1}n$
