In electromagnetic wave, \mathrm{E}_0=\mathrm{B}_0 \mathrm{C}

\begin{aligned} & E_0=6 \times 10^{-7} \times 3 \times 10^8 \\ & =18 \times 10^1 \\ & =180 \mathrm{v} / \mathrm{m} \end{aligned}                 

E_0 \rightarrowAmplitude of electric field

\mathrm{B}_0\rightarrowAmplitude of magnetic field

C\rightarrowSpeed of light
