Question

For a plane electromagnetic wave propagating in $x$-direction, which one of the following combination gives the correct possible directions for electric field ($E$) and magnetic field ($B$) respectively?

Accepted Answer

Direction of propagation of electromagnetic waves is along $\vec{E} 	imes \vec{B}$. Given that direction of propagation is along $x$-axis. Checking option (2): $(-\hat{j} + \hat{k}) 	imes (-\hat{j} - \hat{k}) = 2\hat{i}$. This matches the propagation direction.
