What was Hertz's experimental method for detecting radio waves?
My method involved creating oscillations of very high frequency and then detecting the resulting electromagnetic disturbances. I utilized a spark-gap transmitter, where a rapidly oscillating electric discharge generated these waves. To detect them, I employed a simple loop of wire with a small spark gap. When electromagnetic waves of the appropriate frequency passed through this loop, they induced a current that was sufficient to produce a tiny spark across the detector's gap. The existence and properties of these sparks, however faint, served as empirical proof of the waves' presence and propagation, aligning precisely with Maxwell's predictions.
