Polarization By Reflection And Brewster's Law - Practice Questions & MCQ

 Brewster’s law- 

Brewster discovered that when a beam of unpolarized light is reflected from a transparent medium (refractive index $=\mu$ ), the reflected light is completely plane polarised at a certain angle of incidence (called the angle of polarisation i.e $\theta_p$ ).

And also $\mu=\tan \theta_p$.
i.e For $i=\theta_P$
reflected rays will be completely polarised.
For $i<\theta_P$ or $i>\theta_P$
reflected rays will be partially polarised.
