If Electric field intensity of a uniform plane electro magnetic wave is given as E =-301.6 sin ( k z-ω t ) a_x+452.4 sin ( k z-ω t ) a_y V/m. Then,…

If Electric field intensity of a uniform plane electro magnetic wave is given as $$\mathrm{E}=-301.6 \sin (\mathrm{k} z-\omega \mathrm{t}) \hat{\mathrm{a}}_x+452.4 \sin (\mathrm{k} z-\omega \mathrm{t}) \hat{\mathrm{a}}_y \frac{\mathrm{~V}}{\mathrm{~m}} . $$ Then, magnetic intensity ' H ' of this wave in $\displaystyle \mathrm{Am}^{-1}$ will be : [Given : Speed of light in vacuum $\displaystyle \mathrm{c}=3 \times 10^8 \mathrm{~ms}^{-1}$, Permeability of vacuum $$\left.\mu_0=4 \pi \times 10^{-7} \mathrm{NA}^{-2}\right] $$
