Physics. The vibration of a system exposed to a periodic force whose frequency is equal to the natural frequency of the system. The change in amplitude occurring as the frequency of the wave approaches or coincides with a natural frequency of the medium. Resonant frequencies are about 70 MHz for adults and 100 MHz for children.
