If `vec E` and `vec B` representelectric and magnetic field vectors of an electromagnetic wave, the direction of propagation of the wave is along

Options

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

Answer

C

Explanation

According to electromagnetic wave property, the electric field is perpendicular to the magnetic field. The direction of electromagnetic wave propagation will perpendicular to E and B then `E xx B = C`
