Which of the following pairs of space and time varying $E = (i E_{x} + j E_{y} + k E_{z})$ and $B = (i B_{x} + j B_{y} + k B_{z})$ would generate a plane electromagnetic wave travelling in the z-direction?

Solution

The correct option is C $E_{x}, B_{y}$
$\to E = \to C \times \to B$
If wave is propagating in z-direction then electric and magnetic filed should be in x and y direction so option C is correct
