Question

Group I contains x - and y - components of the electric field and Group II contains the type of polarization of light.

Which of the following statements are correct 

(a) Resultant of (1) leads to elliptically polarized

(b) Resultant of (2) leads to circularly polarized

(c) Resultant of (3) leads to linarly polarized

(d) Resultant of (4) leads to Left circularly polarized 

Answer 1

Correct option  (a), (b) and (c) 

Explanation:

The phase difference between E_x and E_y is π/2 with different amplitude. Therefore the resultant will be elliptically polarized.

The phase difference between E_x and E_y is  π/2 with same amplitude. Therefore the resultant will be circularly polarized.

The phase difference between E_x and E_y is 0 with different amplitude. Therefore the resultant will be linarly polarized. 

The phase difference between E_x and E_y is π/4 with same amplitude. Therefore the resultant will be elliptically polarized.
