Resonance length
WebResonance occurs in an air column when the length of the open tube is a multiple of half the wavelength of the sound. The length of the tube is 33 cm. The first resonance occurs at 0.5 wavelengths, so the wavelength of a 512 Hz sound wave is 66 cm. The speed of sound … Mechanical resonance is the tendency of a mechanical system to absorb more energy when the frequency of its oscillations matches the system's natural frequency of vibration than it does at other frequencies. It may cause violent swaying motions and even catastrophic failure in improperly constructed structures including bridges, buildings, trains, and aircraft. When designing obj…
