Heinrich Rudolf Hertz Birth Anniversary


Heinrich Rudolf Hertz, born on 22 February 1857, was a German physicist who first conclusively proved the existence of the electromagnetic waves predicted by James Clerk Maxwell's equations of electromagnetism. He used a spark gap attached to an induction coil and a separate spark gap on a receiving antenna. When waves created by the sparks of coil transmitter were picked up by the receiving antenna sparks would jump its gap as well. The unit of frequency, cycle per second, was named the "hertz" in his honour.
