If `E` and `B` represent electric and magnetic field vectors of the electromagnetic wave, the direction of propagation of eletromagnetic wave is along.

Options

A. `vec(E)`
B. `vec(B)`
C. `vec(B) xx vec(E)`
D. `vec(E) xx vec(B)`

Answer

D

Explanation

The direction of propagation of electromagnetic wave is perpendicular to both electric field vector `vec(E)` and magnetic field vector `vec(B)` i.e., in the direction of `vec(E) xx vec(B)`.
