Question
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 electromagnetic energy transport?
the negative x direction
the positive y direction
the positive x direction
the negative z direction
the negative y direction
Which of these answers is correct?
the negative x direction
the positive y direction
the positive x direction
the negative z direction
the negative y direction

The frequency of the wave is 1.0 ??? 1016 Hz. What is the direction of electromagnetic energy transport? the negative x direction the positive y direction the positive x direction the negative z direction the negative y direction Which of these answers is correct?Explanation / Answer
A wave with electric field will be directed mutually to direction of magnetic field and direction of EM wave, vertically polarized electromagnetic waves of frequency has the electric field oscillating in the vertical direction. Electric field is right angle to it and both are perpendicular to the direction of propagation and hence direction is along negative x axis.
