Question:
An electromagnetic wave travels in vacuum along z-direction:
$E=\left(E_{1} \hat{i}+E_{2} \hat{j}\right) \cos (k z-\omega t)$. Choose the correct options from the following:
(a) the associated magnetic field is given as
$B=\frac{1}{c}\left(E_{1} \hat{i}-E_{2} \hat{j}\right) \cos (k z-\omega t)$
(c) the given electromagnetic field is circularly polarised
(d) the given electromagnetic waves is plane polarised
Solution:
(a) the associated magnetic field is given as
$B=\frac{1}{c}\left(E_{1} \hat{i}-E_{2} \hat{j}\right) \cos (k z-\omega t)$
(d) the given electromagnetic waves is plane polarised
