A plane electromagnetic wave is the superposition of two independent orthogonal plane waves and can be written as a real part of
E = E₁ exp (i[kz - wt])ūx + Ę₂ exp (i[kz. - wt+7]) ü‚where, and ware real E₁E₂
If E₂ = E₁, the electric field vector will describe a trajectory which, seen along the Zaxis from the positive side and looking towards t
he origin, is:
straight at 135 with respect to the + x axis
O circular in counterclockwise direction
straight at 45°with respect to the + x axis.
O circular in clockwise direction
