(N/A) The most significant inference from Maxwell's equations is the existence of electromagnetic waves,which represent the coupled propagation of time-varying electric and magnetic fields in space.
Due to the propagation of these time-varying fields,electromagnetic waves are generated that travel through space at the speed of light,which is $c = 3 \times 10^{8} \text{ m/s}$.
Thus,Maxwell established a fundamental relationship between electric,magnetic,and optical phenomena.
In $1887$,the scientist Heinrich Hertz experimentally produced electromagnetic waves in the laboratory,confirming Maxwell's theoretical predictions. The subsequent application of this technology revolutionized modern communication systems.
