Vedclass · Answer

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

If $\vec{E}$ and $\vec{B}$ represent electric and magnetic field vectors of an electromagnetic wave,the direction of propagation of the wave is along
