Physics - EM Waves Question with Solution | TestHub

The relation between the electric field and magnetic field is given by

$E_0 = c{B}_0$.

The given data is 

$B_0=6\times {10}^{-7} \mathrm{T}$

$c=3\times {10}^8 \mathrm{m} {\mathrm{s}}^{-1}$

Thus, the maximum value of the electric field is

$E_0= \left(3\times {10}^8\right)\times \left(6\times {10}^{–7}\right)=180 \mathrm{V} {\mathrm{m}}^{-1}$.
