Use the Ampere-Maxwell Equation (the last of the 4 Maxwell equations) to derive the wave equation for the magnetic field, using a plane wave in a vacuum propagating in the x-direction, as shown in the figure. The Ampere loop to evaluate is shown as well. Note: this problem is very similar to the one derived in class today for...
