That light is an electromagnetic wave. Maxwell’s work thus unified the domain of electricity, magnetism and light. Hertz, in 1885, experimentally demonstrated the existence of electromagnetic waves. Its technological use by Marconi and others led in due course to the revolution in communication that we are witnessing today.

wavea These boundaries can generally be both active and passive, the active boundaries usually being sources. The transmitted wave then becomes: This intermediate text emphasizes concepts, examples, and problem-solving techniques having wide applicability, and relies only on basic physics and mathematics — rather than electrostatics, magnetostatics, and quasistatics.
In this limit the solution is simple because the transmitted wave inside the conductor propagates almost perpendicular to the interface, which can be shown as follows.
Here our basic building blocks are usually uniform plane waves, but other more compact expansions are typically used if the symmetry of the problem permits, as illustrated in Section 4.
