If `vec(E)` and `vec(B)` represent electric and magnetic field vectors of the electromagnetic wave, the direction of propagation of electromagnetic wave is along

Options

A. Electric field vector, `vecE`
B. Magnetic field vector, `vecB`
C. `vecE xx vecB`
D. `vecB xx vecE`

Answer

C

Explanation

The direction of propagation of the electromagnetic wave is always perpendicular to the plane in which `vecE` and `vecB` lies. So the direction is along the direction of `vecE xx vecB`.
