Step-by-Step Verified Solution
The relation between electric and magnetic field is ,
C =
= C
Electric field component is perpendicular to the direction of magnetic field. Given magnetic field is along y axis,
So, electric field along z axis will be
= B0 C sin (kx + t) v/m
C =
Electric field component is perpendicular to the direction of magnetic field. Given magnetic field is along y
So, electric field along z
