Consider a plane wave that is a superposition of two independent orthogonal plane waves that can be written as the real part of E = E, exp[i (kz – wt)]î + E1 exp[i (kz – wt +7)]j where k, w, E1, and E, are all real. If E1 = E2, the tip of the electric field vector will describe a trajectory that, as viewed along the z-axis from positive z and looking toward the origin, is a counterclockwise circle. O line at 135° to the +æ-axis. clockwise circle. line at 45° to the +x-axis. O random path.
