resonance (iou)



resonance noun. LME.
[French reson(n)ance (mod. resonance) from Latin resonantia echo, from resonant-: see RESONANT, -ANCE.]
a. The reinforcement or prolongation of sound by reflection, as from the walls of a hollow space, or by the synchronous vibration of a neighbouring object; a sound so prolonged, a resonant sound. LME.
H. Allen The last prolonged resonance of the bell..died away.
b. The property of an object of giving rise to this. M17.
Y. Menuhin The resonance of those vaulting walls..aided the single violin.
c. The amplification of the sound of the voice by the bones and cavities of the head and chest. Also Medicine, the sound produced by tapping parts of the body, used as an aid to diagnosis. E19.
d. Mechanics. A condition in which an object or system is subjected to an oscillating force having a frequency at or close to that of a natural vibration of the object or system; the resulting amplification of the natural vibration. L19.
Encyclopedia Britannica Mechanical resonance..built up to such large proportions as to be destructive, as in..the Tacoma Narrows Bridge.
e. Physics etc. A condition in which a particle is subjected to an oscillating influence (as an electromagnetic field or another particle) of such a frequency that energy transfer occurs or reaches a maximum; an instance of this. L19.
f. Electricity. The condition in which a circuit or device produces the largest possible response to an applied oscillating signal, esp. when its inductive and its capacitative reactances are balanced. L19.
g. Astronomy. The occurrence of a simple ratio between the periods of revolution of two bodies about a single primary. E20.
h. Chemistry. = MESOMERISM. E20.
i. Physics & Chemistry. The transition of a particle possessing a magnetic moment between different quantum states in the presence of a magnetic field and electromagnetic radiation of an appropriate frequency; a spectroscopic technique in which such phenomena are observed. M20.
j. Nuclear Physics. A short-lived particle or excited state of a particle, manifested as an increased probability of capture, excitation, etc. at certain defined energies. M20.
fig.
a. A response in parallel or sympathy; a shared feeling or sense; an allusion, connotation, or feature reminiscent of another person or thing, an overtone in thought, art, language, etc. E17.

Comb.: resonance absorption Nuclear Physics absorption of energy or of a particle under conditions of resonance; spec. resonance capture; resonance capture Nuclear Physics absorption of a particle by an atomic nucleus which occurs only for certain well-defined values of particle energy; resonance chamber = RESONATOR 2; resonance energy (a) an energy value at which resonance occurs; (b) Chemistry the extent of stabilization of a molecular structure attributed to mesomerism; resonance fluorescence: in which the light emitted has the same wavelength as that which excites the emission; resonance hybrid Chemistry a molecular structure which is a combination of a number of mesomeric forms; resonance radiation (the radiation emitted in) resonance fluorescence; resonance scattering Nuclear Physics elastic scattering of a particle by an atomic nucleus at an energy of the incident particle for which the scattering cross-section is large compared with that for adjacent energy values (cf. potential scattering s.v. POTENTIAL noun); resonance stabilization Chemistry = resonance energy (b) above.
