Q.

The electric field of a plane electromagnetic wave is given by = $E = E_{0} \hat{i}$ Z cos (kz) cos( $ω t$ )

The corresponding magnetic field $B$ is then given by :

A
$B = \frac{E _{0}}{C} \hat{j}$ sin(kz) cos( $ω t$ )
B
$B = \frac{E _{0}}{C} \hat{j}$ cos(kz) sin( $ω t$ )
C
$B = \frac{E _{0}}{C} \hat{j}$ sin(kz) sin( $ω t$ )
D
$B = \frac{E _{0}}{C} \hat{k}$ sin(kz) cos( $ω t$ )
