(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 3423 , placed in water having refractive index 43. Will this ray suffer total internal reflection on striking the face AC? Justify your answer.

Answer» (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 $\frac{34}{23}$ , placed in water having refractive index $\frac{4}{3}$ . Will this ray suffer total internal reflection on striking the face AC? Justify your answer.
