In an electromagnetic wave, the electric field vector and magnetic field vector are given as $\vec{E} = E_{0} \hat{i}$ and $\vec{B} = B_{0} \hat{k}$ , respectively. The direction of
propagation of electromagnetic wave is along:

Options:

Answer:

Solution:

Direction of propagation $= \vec{E} \times \vec{B} = \hat{i} \times \hat{k} = - \hat{j}$ .
