Acoustic resonance — is the tendency of an acoustic system to absorb more energy when the frequency of its oscillations matches the system s natural frequency of vibration (its resonance frequency ) than it does at other frequencies. A resonant object will probably… … Wikipedia
Wave — A wave is a disturbance that propagates through space and time, usually with transference of energy. While a mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces), waves of electromagnetic… … Wikipedia
