Product Overview
Replicates Heinrich Hertz's experiment on production and detection of electromagnetic waves. Consists of a spark gap transmitter connected to an antenna which radiates the waves and an identically constructed detector or receiver unit.
When an induction coil or Wimshurst machine connected to the transmitter produces a high voltage discharge, a spark jumps across the gap between the two metal spheres, sending out a signal that is detected as a weaker spark across the gap in the receiver, which is placed nearby. Because weak sparks in the receiver are difficult to see, a sensitive neon lamp is connected across the gap between the receiver's two metal spheres. The lamp flashes/glows bright orange when a signal is detected.
You need an induction coil or a Wimshurst machine. It is recommended that the experiment is preformed in a darkened classroom.
