Hertzian \Hertz"i*an\, a.
   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.
