   Resonance
   1) The effect produced when the natural vibration frequency of a body is greatly amplified by reinforcing vibrations at the same or nearly the same frequency from another body.
   2) The prolonging of the sound at a certain frequency and the tendency of something to vibrate at a particular frequency after the source of energy is removed.

   Resonance
   The resonant frequency of a system is defined as the frequency for which the response of the system is a maximum. If the excitation frequency is either increased or decreased the amplitude of response will decrease. See also: Anti Resonance, Quality Factor, Resonant Frequency.

   resonance
   In the context of chemistry, the term refers to the representation of the electronic structure of a molecular entity in terms of contributing structures. Resonance among contributing structures means that the wavefunction is represented by 'mixing' the wavefunctions of the contributing structures. The concept is the basis of the quantum mechanical valence bond methods. The resulting stabilization is linked to the quantum mechanical concept of 'resonance energy'. The term...

9. 
   resonance
   (Learning Modules / Mathematics / Bridges) The build-up of oscillatory, or wave-like, motion in an object such as a plucked guitar string or the deck of a suspension bridge in a wind. The control of such motion requires the removal, or absorption, of the energy of the wave, preventing its build-up.

    Resonance
    In physics, `resonance` is the phenomenon of producing large amplitude of vibrations by a small periodic driving force. It is the tendency of a system to oscillate at maximum amplitude at a certain frequency. This frequency is known as the system's `resonance frequency` (or `resonant frequency`). When damping is small, the resonance frequency is approximately equal to the natural frequency of the system, which is the frequency of free vibrations....

    Resonance
    Usually used to mean 'betatron resonance' when talking about an accelerator; it occurs when some perturbing force in the accelerator distorts the orbit in a periodic way, causing the betatron oscillations to grow larger and larger, until beam is lost or perhaps extracted.
