The Answer of 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 rms value of the magnetic field? Assume that the figure shows the peak value of . A)1.0 × 10^-⁸ T B)1.4 × 10^-⁸ T C)2.8 × 10^-⁸ T D)4.6 × 10^-⁸ T E)5.7 × 10^-⁸ T
