Wave Motion, the surface of a lake, and a sound wave in the air are good examples of traveling waves. There are two types of traveling waves. For instance, the wave in a spring as shown in Fig. 7.1(a) is a longitudinal wave for which the medium is displaced in the same direction as the direction of propagation

The uniform plane wave is an unbounded and unguided wave in the sense that the electric field exists in all space and the electromagnetic energy spreads over the whole space. While a
