In an electromagnetic wave,if the magnetic field points in the -x direction and the electric field points in the +z direction,the wave must be traveling in the +y direction.

Question

By convention, the direction of the electric field vector is used to define the direction of electromagnetic wave propagation. Therefore, if the electric field is pointing in the +z direction (along the z-axis), then the wave must be traveling in the +z direction. The direction of the magnetic field relative to the electric field determines the polarization of the wave (i.e. the orientation of the electric field oscillations), but not the direction of propagation.
