The electric field and magnetic field components of an electromagnetic wave going through vacuum is described by $$\begin{aligned} & \mathrm{E}_x=\mathrm{E}_{\mathrm{o}} \sin (\mathrm{kz}-\omega \mathrm{t}) \\ & \mathrm{B}_y=\mathrm{B}_{\mathrm{o}} \sin (\mathrm{kz}-\omega \mathrm{t}) \end{aligned} $$ Then the correct relation between $\displaystyle \mathrm{E}_{\mathrm{o}}$ and $\displaystyle \mathrm{B}_{\mathrm{o}}$ is given by
