Question

If `E` and `B` represent electric and magnetic field vectors of the electromagnetic wave, the direction of propagation of eletromagnetic wave is along.
A. `vec(E)`
B. `vec(B)`
C. `vec(B) xx vec(E)`
D. `vec(E) xx vec(B)`

Answer 1

Correct Answer - D
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)`.
