Multiple choice:
If the electric field in a plane electromagnetic wave is along the y axis and its components is given by Em sin(kx + wt) In SI units, then the magnetic field is along the z axis and its component given by (Em / c) cos(kx + wt ) -(Em / c) cos(kx + wt) -(Em / c)sin(kx + wt) (Em / c)sin(kx + wt )
