Vedclass · Answer

(a)${E_x}$ and ${B_y}$ would generate a plane EM wave travelling in $z$-direction. $\vec E$, $\vec B$ and $\vec k$ form a right handed system $\vec k$ is along $z$-axis. As $\hat i 	imes \hat j = \hat k$
==> ${E_x}\hat i 	imes {B_y}\hat j = C\hat k$ i.e. $E$ is along $x$-axis and $B$ is along $y-$ axis.
