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.
-What is the direction of polarization of this electromagnetic wave?

• A)the x direction
• B)the y direction
• C)the z direction
• D)45° with respect to the x direction
• E)the wave is not polarized
