Can reflection result in plane polarised light if the light is incident on the interface from the side with higher refractive index?
Text solutionVerified
When angle of incidence is equal to Brewster's angle, the transmitted light is unpolarised and reflected light is plane polarised.
Consider the diagram in which unpolarised light is represented by dot and plane polarised light is represented by arrows.
Polarisation by reflection occurs when the angle of incidence is the Brewster's angle
where
when the light rays travels in such a medium, the critical angle is
where,
As for large angles

A polaroid (I) is placed in front of a monochromatic source. Another polaroid (II) is placed in front of this polaroid (I) and rotated till no light passes. A third polaroid (III) is now placed in between (I) and (II). In this case, will light emerge from (II). Explain.

In 1964, a Russian scientist V. Veselago postulated the existence of material with and . Since, then such metamaterials have been produced in the laboratories and their optical properties studied. For such materials . As light enters a medium of such refractive index the phases travel away from the direction of propagation.
(i) According to the description above show that if rays of light enter such a medium from air (refractive index ) at an angle in 2 nd quadrant, then the refracted beam is in the 3rd quadrant.
(ii) Prove that Snell's law holds for such a medium.
