The electric field and magnetic field oscillate in opposite phase

Vedclass · Answer

(D) The correct answer is $D$. In a plane electromagnetic wave,the electric field $\vec{E}$ and the magnetic field $\vec{B}$ oscillate in the same phase. They are perpendicular to each other and also perpendicular to the direction of wave propagation. Since they oscillate in the same phase,the statement that they oscillate in opposite phase is incorrect. Additionally,the average energy density of the electric field is equal to the average energy density of the magnetic field,i.e.,$u_E = u_B = \frac{1}{4} \epsilon_0 E_0^2$.
