As these waves pound against the sea floor, they generate a constant vibration with a frequency of about ten millihertz, much too low for humans to hear but easily detectable with seismometers.

Maxwell showed that light was a vibration in the electromagnetic field, and that it travelled at a constant speed, c, in a vacuum.

The result shows, under different vibration mode, equivalent parallel capacitance and resistance are not constant value. There is negative damp effect in transducer system at the operating mode.
