The instantaneous electric E-Field of a 1 MHz plane wave traveling in the +z direction in air points along the x-direction. If this field reaches a peak value of 1.2n (mV/meter) at t = 0 and z = 50 m., obtain expressions for the instantaneous electric field E(x,y,z,t) and the instantaneous magnetic field H(x, y, z, t). Then plot these fields on a single plot as a function of z > 0 at time t = 0.
