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 × 10 16 Hz.
-What is the direction of the electric field?
A)It points in the negative y direction.
B)It points in the positive y direction.
C)It points in the negative z direction.
D)It points in the negative x direction.
E)It points in the positive x direction.
