The electric field of a' plane electromagnetic wave in vacuum is represented by:`E_(x)=0` `E_(y)=0.5 cos [2 pi xx 10^(8)(t-(x)/(c))]E_(z)=0`
All the quantities are is SI units. If the component of magnetic field associated with the wave is `n xx 10^(-8) cos [2 pi xx 10^(8)(t-(x)/(c))]` tesla, then find `n .`
