WebMaxwell explained that electric and magnetic waves can be generated by oscillating electric charges. These electromagnetic waves may be depicted as crossed electric and magnetic fields propagating through space perpendicular to the direction of motion and to each other, as illustrated in Figure 3. James Clerk Maxwell derived a wave form of the electric and magnetic equations, thus uncovering the wave-like nature of electric and magnetic fields and their symmetry. Because the speed of EM waves predicted by the wave equation coincided with the measured speed of light, Maxwell concluded that light itself is an EM wave. Maxwell's equations were confirmed by Heinrich Hertz through ex…
