(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.
In particle physics, a resonance is the peak located around a certain energy found in differential cross sections of scattering experiments. These peaks are associated with subatomic particles (such as nucleons, delta baryons, upsilon mesons) and their excitations. The width of the resonance (Γ) is related to the lifetim...Found on http://en.wikipedia.org/wiki/Resonance_(particle_physics)
A relationship in which the orbital period of one body is related to that of another by a simple integer fraction, such as 1/2, 2/3, 3/5.

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.

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.

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.

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.
