Hertzian oscillator

His genius found its first occasion at the University of New Zealand, where Rutherford in 1893 stayed on to earn a B.Sc. Heinrich Hertz s 1887 discovery of electric waves — radio, we call the phenomenon now—had impressed Rutherford wonderfully, as it did young people everywhere in the world. To study the waves he set up a Hertzian oscillator—electrically charged metal knobs spaced to make sparks jump between metal plates—in... 

The sphere was oscillated at a fiequency of 5 Hz. The linear motor maintained the pin motionless for 20 ps at the end of each stroke. In this way the stroke length of5 mm corresponded to a sliding speed of 62 mm/s. The applied load was 5 N, resulting in a starting Hertzian pressure of -1.7 MPa.
