Of or pert. to the German physicist Heinrich Hertz.

{Hertzian telegraphy}, telegraphy by means of the Hertzian
waves; wireless telegraphy.

{H. waves}, electric waves; -- so called because Hertz was
the first to investigate them systematically. His
apparatus consisted essentially in an oscillator for
producing the waves, and a resonator for detecting them.
The waves were found to have the same velocity as light,
and to undergo reflection, refraction, and polarization.
