Can reflection result in plane polarised light if the light is incident on the interface from the side with higher refractive index?

How can you detect a polarised light?

Can our eye distinguish polarised light from unpolarised light?

A substance which rotates the plane of polarised light to the right are designated by the sign:

The refractig angle of a prism is A and the refractive index of its material is mu .When a ray of light is incident on the face AB of the prism,after refraction through the prism,the ray of light just grazes along the face AC as shown in Fig.3.21. Determine the value of the angle of incidence in terms of A and mu .

A beam of unpolarised light is incident on the boundary between two transparent media.If the reflected light is completely plane polarised,how is its direction related to the direction of the corresponding refracted light?

Polarised light can be produced by

Refractive indices of water and glass are 4//3 and 3//2 respectively.A ray of light travelling in water is incident on the water-glass interface at 30^@ .Calculate the angle of refraction.
