The Electromagnetic Wave of the Radiation Field from a Wire

question 31

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 rms value of the electric field? Assume that the figure shows the peak value of .

• A)7.5 N/C
• B)8.5 N/C
• C)17 N/C
• D)1.1 × 10⁴ N/C
• E)8.5 × 10^-3 N/C
