Vedclass · Answer

(B) Statement $A$ is incorrect because the direction of propagation is perpendicular to both the electric and magnetic fields,not along them.
Statement $B$ is correct; in an electromagnetic wave,the energy density is shared equally between the electric field $(u_E = \frac{1}{2} \epsilon_0 E^2)$ and the magnetic field $(u_B = \frac{1}{2} \frac{B^2}{\mu_0})$,such that $u_E = u_B$.
Statement $C$ is incorrect because the electric and magnetic fields are perpendicular to each other.
Statement $D$ is correct; electromagnetic waves are transverse in nature,meaning $\vec{E}$,$\vec{B}$,and the direction of propagation $\vec{k}$ are mutually perpendicular.
Statement $E$ is incorrect because the ratio of the amplitude of the electric field to the magnetic field is equal to the speed of light $(E_0/B_0 = c)$,so $B_0/E_0 = 1/c$.
Therefore,only statements $B$ and $D$ are correct.
