### 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

Description of the ground state of a molecule with delocalized electrons as an average of several Lewis structures. The actual ground state doesn't switch rapidly between the separate structures: it is an average.

### Resonance

In physics, resonance is the tendency of a system to oscillate with greater amplitude at some frequencies than at others. Frequencies at which the response amplitude is a relative maximum are known as the system`s resonant frequencies, or resonance frequencies. At these frequencies, even small periodic driving forces can produce large amplitude o....

### Resonance

• (n.) An electric phenomenon corresponding to that of acoustic resonance, due to the existance of certain relations of the capacity, inductance, resistance, and frequency of an alternating circuit. • (n.) A prolongation or increase of any sound, either by reflection, as in a cavern or apartment the walls of which are not distant enough t...

### resonance

(rez´o-nәns) the prolongation and intensification of sound produced by transmission of its vibrations to a cavity, especially such a sound elicited by percussion. Decrease of resonance is called dullness; its increase, flatness. a vocal sound heard on auscultation. mesomerism.

### 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

[chemistry] In chemistry, resonance or mesomerism is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis formula. A molecule or ion with such delocalized electrons is represented by several contributing structures (also called resonance structures or...

### Resonance

[particle physics] 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...

### Resonance

A frequency at which a material object will vibrate. In a filter with resonance, a signal will be accentuated at the cutoff frequency. The characteristic of a filter that allows it to selectively pass a narrow range of frequencies. See Q

### resonance

A function on a filter in which a narrow band of frequencies (the resonant peak) becomes relatively more prominent. If the resonant peak is high enough, the filter will begin to oscillate, producing an audio output even in the absence of input. Filter resonance is also known as emphasis and Q. It is also referred to in some older instruments as reg...
