When AC power is applied to the meter, the reed closest in frequency to the signal will vibrate more than the others, causing an audible tone at that frequency. This is shown in the image below.

For water waves and sound waves the unit hertz is usually good enough but radio and TV waves have such a high frequency that the kilohertz (\(kHz\)) or even the megahertz (\(MHz\)) are better units.
