JEE MainPhysicsModerateEM wave

A plane electromagnetic wave is propagating along the
direction $\frac{\overset{\hat{}}{\mathbf{i}} + \overset{\hat{}}{\mathbf{j}}}{\sqrt{2}}$ ,
with its polarization along the direction $\widehat{k}$ . The correct form
of the magnetic field of the wave would be (here B0 is an
appropriateconstant)

Show answer and solution

EM wave is in
direction

\ \rightarrow \frac{\overset{\hat{}}{i} + \overset{\hat{}}{j}}{\sqrt{2}}

.
Electric field is in direction

\ \rightarrow \overset{\hat{}}{k}

\overset{\rightarrow}{E} \times \overset{\rightarrow}{B} \rightarrow

Direction of propagation of EM wave
Therefore, B is along

\frac{\overset{\hat{}}{i} - \overset{\hat{}}{j}}{\sqrt{2}}
