There are are two parallel planes. They are perpendicular to the
z-axis and run parallel to the xy plane. The two planes are a
distance X apart. The two planes are perfect conductors and the
magnetic and electric fields propagate in a wave between the two
planes traveling in the x-direction. If electric field is
given the value of "E" use elements like displacement to find the
applicable boundary conditions. Solve for the traveling wave
equation if the velocity of the waves is assumed to be
"c," the speed of light.
