Each trial description such electromagnetic theory of Maxwell, Hertz Hall, and there is also conducted and the results concluded that "electromagnetic waves have a speed equal to the speed of light".
Each experiment the description supports the theory of electric magnetic waves, Maxwell and Hertz also has tested so far have concluded that "electromagnetic waves with speed equal to the speed of light," he said.
The description of each experiment and theory of electromagnetic waves Maxwells Hz and, in addition to the conclusion that "trial until it was electromagnetic waves with a speed equal to the speed of light".
