2. (a) Write and describe the Maxwell's Equations in vacuum. (b) i) ii) iii) Derive the wave equation for electric field E Write the expression for the plane-wave solutions to the wave equation in i). Show that the electric field E has no component parallel to the direction of wave propagation. (c) A monochromatic plane wave of amplitude Eo, frequency , and phase angle zero is traveling in the negative z direction and polarized in the z direction in vacuum. i) Write down the expressions for the (real) electric E(r, t) and magnetic B(r, t) fields. ii) If the intensity I of the electromagnetic wave is 133 W/m², determine the average energy flux density (S) and average momentum density (g) of the wave.
