Vedclass · Answer

(C) An electromagnetic wave consists of oscillating electric and magnetic fields that are perpendicular to each other and to the direction of wave propagation.According to the properties of electromagnetic waves,the direction of propagation is given by the Poynting vector $\vec S$,which is defined as $\vec S = \frac{1}{\mu_0} (\vec E 	imes \vec B)$.Since $\mu_0$ is a positive constant,the direction of the wave propagation is the same as the direction of the cross product of the electric field vector $\vec E$ and the magnetic field vector $\vec B$.Therefore,the direction of propagation is $\vec E 	imes \vec B$.

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