Answer:
Electric field will move in y-direction, while magnetic field will move in z-direction.
Explanation:
If we make a sketch of electromagnetic wave propagation, we will discover that, the direction of the electric field will be towards y-direction and the direction of the magnetic field will be towards z-direction.
Therefore, if electromagnetic wave with electric field is incident on the conductor, immediately after reflection, Electric field will move in y-direction, while magnetic field will move in z-direction.
