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 Brewsters angle for two media is given by \[\tan {{i}_{B}}=\frac{{{n}_{2}}}{{{n}_{1}}}=\frac{3}{2}\] \[\Rightarrow \] \[{{i}_{B}}={{\tan }^{-1}}(3/2)\approx 56{}^\circ \] Clearly, \[i=\theta \ne {{i}_{B}}\] Thus, reflected light is not plane polarized. It will be partially polarized.You need to login to perform this action.
