When light is polarised by reflection, what is the plane of vibration of the electric field vector in polarised light?

A ray of light is incident on a medium at the polarising angle. What is the angle between the reflected and refracted rays?

If the polarising angle for air-glass interface is $56°$, what will be the angle of refraction in glass?

The critical angle for a given transparent medium and air is $i_c$. A ray of light travelling in air incident on this transparent medium at an angle of incidence equal to the polarising angle $i_p$. What is the relation between the two angles $i_c$ and $i_p$?

Why are two images observed of an object which is being seen through a calcite crystal?

Two Polaroids $A$ and $B$ are parallel and ordinary light falls on $A$. What will be the intensity of light emerging from $B$ compared to that of ordinary light? If $A$ and $B$ are perpendicular, then?
