An electromagnetic plane wave is traveling through a vacuum along the positive z-axis. At a particular point in space at one instant in time the electric field vector is E=i(6V/m) + j(6 V/m). (a) Find the magnetic field vector at the same point in space and instant in time. (b) Find the poynting vector at the same point in space and instant in time.
