Successive iterative solutions of the geometrical optics are explicitly obtained for a conducting wedge of arbitrary wedge angle. Their convergence to the exact edge diffraction pattern is shown numerically. Only one iteration is needed to give a better approximation for edge diffraction than the physical optics approximation.
