Physics - EM Waves Question with Solution | TestHub

Given magnetic field,$\overrightarrow{B}=1.6\times {10}^{-6}\mathrm{c}\mathrm{o}\mathrm{s}\left(2\times {10}^{7}z+6\times {10}^{15}t\right)\left(2\widehat{i}+\widehat{j}\right)\frac{\mathrm{W}\mathrm{b}}{{\mathrm{m}}^2}$
The relation between magnetic field and electric field is$E=cB=(3\times {10}^8)\times (1.6\times {10}^{-6}\times \sqrt{5})=4.8\times {10}^2\times \sqrt{5}$
The direction of light propagation will be along$\overrightarrow{E}\times \overrightarrow{B}$.
$\overrightarrow{E}=4.8\times {10}^2\mathrm{c}\mathrm{o}\mathrm{s}\left(2\times {10}^{7}z+6\times {10}^{15}t\right)\left(-\widehat{i}+2\widehat{j}\right)\frac{\mathrm{V}}{\mathrm{m}}$
