The principle being employed is resonance, which occurs when two objects with similar natural frequencies interact and one begins to vibrate in response to the other. In this case, the internal electrical circuit of the radio is designed to vibrate at a specific frequency, and when the radio is tuned to a particular station, it is adjusted to vibrate in resonance with the frequency of the radio station's signal.
