Polarization — CSIR Net PYQ (Question 2)

A Polarization previous-year question (PYQ) from Optics (CSIR Net). Read the question, check the correct answer, then practise the full topic.

Question 2 of 5 · 3.5 marks

The electric field of an electromagnetic wave is

E (z, t) = E_{0} cos (k z + ω t) \overset{ı}{^} + 2 E_{0} s in (k z + ω t) \overset{ȷ}{^}

, where

ω

and

k

are positive constants. This represents

1a linearly polarised wave travelling in the positive z-direction
2a circularly polarised wave travelling in the negative $z$ -direction
3an elliptically polarised wave travelling in the negative $z$ -direction
4an unpolarised wave travelling in the positive z-direction

Correct answer: Option 3
