If $\vec{E}$ and $\vec{B}$ are the electric and magnetic field vectors of an electromagnetic wave, then the direction of propagation of the electromagnetic wave is
along the direction of $\overrightarrow{\mathrm{E}}$
along the direction of $\overrightarrow{\mathrm{B}}$
parallel to the direction of $\overrightarrow{\mathrm{E}} \times \overrightarrow{\mathrm{B}}$
perpendicular to the direction of $\overrightarrow{\mathrm{E}} \times \overrightarrow{\mathrm{B}}$
Solution
The direction of propagation of the electromagnetic wave is perpendicular to the direction of $\overrightarrow{\mathrm{E}} \times \overrightarrow{\mathrm{B}}$.
