The magnetic field in a plane electromagnetic wave is given by B_(y)=(2xx10^(-7)) T sin (0.5xx10^(3)x+1.5xx10^(11)t). Write an expression for the electric field. |

Answer» Solution :`E_(o) =B_(o)c =2xx10^(-7) Txx 3XX10^(8) m//s =6XX10^(1) V//m` The electric FIELD component is perpendicular to the direction of propagation and the direction of magnetic field. Therefore, the electric field component along the z-axis is obtained as `E_(z) =60 SIN (0.5 xx10^(3) x +1.5 xx10^(11) t) V//m` |
