The Electromagnetic Wave of the Radiation Field from a Wire

question 17

Multiple Choice

The electromagnetic wave of the radiation field from a wire antenna travels toward the plane of your paper (which is in the -z direction) . At time t = 0 s, the wave strikes your paper at normal incidence. The magnetic field vector at point O in the figure points in the -y direction and has a magnitude of 4.0 × 10-8 T. The frequency of the wave is 1.0 × 1016 Hz. The electromagnetic wave of the radiation field from a wire antenna travels toward the plane of your paper (which is in the -z direction) .
