The properties of plane electromagnetic waves are derived without the use of calculus in a manner which provides a fundamental understanding of isolated waves far removed from their sources or any guiding conductors. The symmetrical relationship of the induced electric field to the induced magnetic field and the role of the displacement current are clearly demonstrated. Expressions for the velocity of the wave and the magnitudes and directions of the fields are derived. These results are developed directly from basic induced field concepts, thus avoiding the complications arising in the traditional transmission line approach which of necessity involves free charges and conduction currents.
