1. Quarter wave plate
2. Half wave plate
3. Both a and b
4. ve > vo
5. 2

1. A quarter wave plate is used for producing elliptically or circularly polarized light. It depends on the angle the incident light vector makes with the optic axis of the quarter wave plate.

2. Half wave plate introduces a phase difference of 1800 between extraordinary ray and ordinary ray. It also creates a path difference of λ/2 between them.

3. When the optical path difference is λ/4, the resultant wave can be both elliptically and circularly polarized. Linear polarization occurs when the optical path difference is λ/2.

4. Birefringence of the crystal, n = ne-no

So it’s negative means, ne < no

Refractive index(n) is inversely proportional to the velocity of o-ray and e-ray.

Hence, ve > vo .

5. In one full rotation of the polarizer, we get two positions of maximum intensity and two positions of zero intensity- then we say it’s linearly polarized.
