Options:
  • A \( \vec{E} \)
  • B \( \vec{B} \)
  • C \( \vec{E} \times \vec{B} \)
  • D \( \vec{B} \times \vec{E} \)

The correct answer is: \( \vec{E} \times \vec{B} \)
The direction of proportion of electromagnetic wave is perpendicular to the electric and magnetic field vectors. Therefore,
the direction of propagation of wave is along \( \vec{E} \times \vec{B} \).
