  • D.C. Powerpak
  • Hertz's apparatus
  • Fluorescent tube

Hertz Apparatus

Hertz Apparatus Setup.

Description

The induction coil is connected to Hertz's apparatus which consists of a pair of large square plates separated by a spark gap. The approximate values for L and C in this arrangement yields a resonant frequency of ~ 55MHz  Î»=5.4 metres.

The production of electromagnetic waves is demonstrated by the lighting of a fluorescent tube.
