Vedclass · Answer

(C) In an electromagnetic wave,the electric field vector $\overrightarrow{E}$ and the magnetic field vector $\overrightarrow{B}$ oscillate in phase and are mutually perpendicular to each other.According to Maxwell's equations and the properties of electromagnetic waves,the direction of propagation of the wave is given by the direction of the Poynting vector $\overrightarrow{S}$,which is defined as $\overrightarrow{S} = \frac{1}{\mu_0} (\overrightarrow{E} 	imes \overrightarrow{B})$.Therefore,the direction of propagation of the electromagnetic wave is along the direction of $\overrightarrow{E} 	imes \overrightarrow{B}$.

If $\overrightarrow{E}$ and $\overrightarrow{B}$ are the electric and magnetic field vectors of electromagnetic waves,then the direction of propagation of the electromagnetic wave is along the direction of
