The first evidence for electromagnetic waves came from
A) Heinrich Hertz's experiments in which electrons jumped back and forth across a gap in an electric circuit and EM waves were detected at some distance from the gap.
B) Marconi's experiment in which sound waves were sent from a vibrating membrane in one city and received by a similar device in another city.
C) Marconi's experiment in which radio waves were sent from a piece of vibrating crystal in one city and received by a similar device in another city.
D) Heinrich Hertz's experiments in which electric charge was placed on small wooden rod and set into rapid vibration; EM waves were detected by a second wooden rod at some distance from the first rod.
E) Maxwell's experiments in which magnetic effects were demonstrated to result from the current in electrical circuits.
