The Principle Of Resonance
The scientific principle of resonance is defined as the increase in the amplitude of the oscillation of one system exposed to a periodic force whose frequency is equal to or nearly the same as the frequency of another system. This principle can be demonstrated easily. For example: when two violins are in a room together and they are tuned the same - if you pluck the G string on one violin, the G string on the violin across the room will vibrate.
The same principle of resonance occurs when you offer twenty dollars to pluck the G string on stripper, another stripper across the room will give you the same deal.
