Q)

# A plane electro magnetic wave propagating along x - direction can have following pair of $\overrightarrow{E}$ and $\overrightarrow{B}$

$\begin{array}{1 1} E_x ,B_y \\ E_y,B_z \\ B_x,E_y \\ E_z,B_y \end{array}$

Electric field and magnetic field $\overrightarrow{E}$. and $\overrightarrow{B}$ and perpendicular to each other and also perpendicular to the direction of propagation of the em wave .
Answer : $E_y,B_z$
