Question

The light is incident from air to a medium of the refractive index $\frac{4}{3}$. The Brewster's angle for this scenario will be

• A. ${37}^o$
• B. ${45}^o$
• C. ${53}^o$
• D. ${90}^o$

Answer 1

The correct option is C ${53}^o$

By Brewster's law
$\mu =\tan i_p$
$i_p={\tan }^{-1}\left(\mu \right)$
$={\tan }^{-1}\left(\frac{4}{3}\right)$
$={53}^{\circ }$
