Q. If $\overrightarrow{E}$ and $\overrightarrow{B}$ are the electric and magnetic field vectors of E.M. waves then the direction of propagation of E.M. wave is along the direction of
A) $\overrightarrow{E}$
B) $\overrightarrow{B}$
C) $\overrightarrow{E} \times \overrightarrow{B}$
D) None of these
Explanation
(c) EM waves travels perpendicular to $E$ and $B$. Which are also perpendicular to each other $\overrightarrow{v} = \overrightarrow{E} \times \overrightarrow{B}$
