Question

Unpolarized light is incident on a plane glass surface The angle of incidence so that reflected and refracted rays are perpendicular to each other, then

• A. $\tan i_{\beta} = \frac{\mu}{2}$
• B. $\tan i_{\beta} = \mu$
• C. $\sin i_{\beta} = \mu$
• D. $\cos i_{\beta} = \mu$

Answer 1

Answer: (B)

$\tan i_{\beta} = \mu$

Answer 2

Brewster’s law is given by

$\mu = \tan i_{\beta}$
