Document Summary
Resonance: the tendency of a system to vibrate with greatest amplitude in response to a frequency that matches or comes close to its own natural frequency (analogy: the swing is set into vibration in response to you pushing it) Natural frequency (nf): the frequency at which an object vibrates freely and is determined by the objects length, density, tension and stiffness. Tuning fork 1 supplies the applied/driving frequency and tuning fork 2 is the resonator. Applied/driving frequency: frequency that acts as an input to a resonator. Resonator: object that vibrates in response to another vibration; can be mechanical or acoustic. Resonant frequency (rf): frequency at which the resonance occurs; frequency at which the resonator undergoes the greatest vibratory response. Half-wave resonator: tube open at both ends; only one half of a wave fits in the resonator at any one time.
