A) Reflected light will be partially polarized
B) Reflected light will be plane polarised in a plane perpendicular to plane of incidence
C) Refracted light will be plane polarised in a plane perpendicular to plane of incidence
D) Refracted light will be plane polarised in a plane parallel to plane of incidence
Correct Answer: A
Solution :
Consider the situation shown below Brewster's angle for two media is given by \[\tan \,\,{{i}_{B}}=\frac{{{n}_{2}}}{{{n}_{1}}}=\frac{3}{2}\] \[\Rightarrow \] \[{{i}_{B}}={{\tan }^{-1}}(3/2)={{56}^{o}}\] Clearly, \[i=\theta \ne {{i}_{B}}\] Thus, reflected light is not plane polarised. It will be partially polarised.You need to login to perform this action.
