The direction of transmission of electromagnetic wave is A) Parallel to E (vector) B) Parallel to B (vector) C) Parallel to B (vector) x E (vector) D) Parallel to E (vector) x B (vector) |

Answer» The correct option is D) Parallel to E (vector) x B (vector). E is the electric field vector, and B is the magnetic field vector of the EM wave. For electromagnetic waves E and B are always perpendicular to each other and perpendicular to the direction of propagation. The direction of propagation is the direction of E x B. |
