(a) Show using a proper diagram how unpolarised light can be linearly polarised by reflection from a transparent glass surface.
(b) The figure shows a ray of light falling normally on. the face AB of an equilateral glass prism having refractive index 3/2, placed A in water of refractive index 4/3. Will this ray suffer total internal reflection on striking the face AC? Justify your answer.

A

reflected and refracted rays are mutually perpendicular

B

Both reflected and refracted rays are plane polarised

C

refracted ray is partially polarised

D
