A plane electromagnetic wave of frequency 100 MHz is travelling in vacuum along the x-direction . At a particular point in space and time $\vec{B} = 2.0 \times 10^{- 8} \hat{k} T .$ (Where, $\hat{k}$ is unit vector along z-direction of light ). What is $\vec{E}$ at this point ?
(speed of light $c = 3 \times 10^{8} m / s$ )

Question

Infinity Learn · Accepted Answer

$$E0=B0c$$ ⇒$$E0=3$$×$$108$$×$$2$$×$$10$$−$$8$$ ⇒$$E0=6$$ $$V/m$$ Direction of electric field is given by, $$E^=B^$$×$$V^=k^$$×$$i^=j^$$
