An electromagnetic wave travelling along the z-axis is given as: E=E_{0} \cos (k z-\omega t). Choose the correct options from the following a) the associated magnetic field is given as B=\frac{1}{c} \hat{k} \times E=\frac{1}{\omega}(\hat{k} \times E)
b) the electromagnetic field can be written in terms of the associated magnetic field asE=c(B \times \hat{k})
c)\hat{k} \cdot E=0, \hat{k} \cdot B=0
d)\hat{k} \times E=0, \hat{k} \times B=0

a) the associated magnetic field is given as
B=\frac{1}{c} \hat{k} \times E=\frac{1}{\omega}(\hat{k} \times E)

b) the electromagnetic field can be written in terms of the associated magnetic field asE=c(B \times \hat{k})
