A plane electromagnetic wave of frequency $\displaystyle 25$ GHz is propagating in vacuum along the $\displaystyle z$-direction. At a particular point in space and time, the magnetic field is given by $\displaystyle \overrightarrow{\mathrm{B}}=5 \times 10^{-8} \hat{j} \mathrm{~T}$. The corresponding electric field $\displaystyle \vec{E}$ is (speed of light $\displaystyle \mathrm{c}=3 \times 10^8 \mathrm{~ms}^{-1}$ )
