A plane electromagnetic wave travels in free space along the $\displaystyle x$-direction. The electric field component of the wave at a particular point of space and time is $\displaystyle \mathrm{E}=6 \mathrm{Vm}^{-1}$ along $\displaystyle y$-direction. Its corresponding magnetic field component, B would be :
Official answer
(1)
