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

Options

A. `sin^(-1)(mu)`
B. `sin^(-1)(1//mu)`
C. `tan^(-1)(1//mu)`
D. `tan^(-1)(mu)`

Answer

D

Explanation

According to Brewster.s law of polarization,
`mu=tani_(p)` where `i_(p)` is angle of incidence
`:.i_(p)=tan^(-1)(mu)`.
