Question

An electromagnetic wave travelling along z-axis is given as-E=E0 cos (kz – cot). Choose the incorrect option from the following;
(a) The associated magnetic field is given as B = \frac{1}{c}\hat{k} × E = \frac{1}{\omega}(\hat{k} × E)
(b) The electromagnetic field can be written in terms of the associated magnetic field as E = c(B × \hat{k})
(c) \hat{k}.E = 0, \hat{k}.B =0.
(d) \hat{k} × E = 0, k\hat{k} × B = 0.
