More example sentences

1.1The ability to evoke or suggest images, memories, and emotions: the concepts lose their emotional resonance
More example sentences

- Instead of the usual light-hearted romp, this performance found power and emotional resonance in the music.
- They are completely unaware of who this monument celebrates or what its significance is; yet the image's resonance is not lost on its audience.
2 Physics The reinforcement or prolongation of sound by reflection from a surface or by the synchronous vibration of a neighboring object.
- A special kind of sound reinforcement, called assisted resonance, is used in some halls to increase the reverberation time within certain frequency bands.
- The researcher believes giraffes may use Helmholtz resonance, causing the air in their long windpipes to vibrate at a low pitch.
- A bass trap is any device that reduces the strength of a low frequency ‘standing wave’ or resonance.
3The condition in which an electric circuit or device produces the largest possible response to an applied oscillating signal, especially when its inductive and its capacitative reactances are balanced.
- The piezo transformer is operated as close to resonance as possible, contributing to greater circuit efficiency.
- On the other hand, if the electrical resonance is involved in the generation of oscillations, disabling it should eliminate the spontaneous bundle activity.
- In addition, the signal overlap for each resonance line can be examined in the spatially resolved spectra.
3.1 Mechanics The condition in which an object or system is subjected to an oscillating force having a frequency close to its own natural frequency.
- He found that, at a certain speed, the resonance - or natural frequency - of the machine was the root cause of the problem.
- Selective resonance at these eigentone frequencies will inevitably colour the sound, especially in small rectangular rooms where the resonant frequencies are high enough to fall within the musical range.

4 Astronomy The occurrence of a simple ratio between the periods of revolution of two bodies about a single primary.

5 Chemistry The state attributed to certain molecules of having a structure that cannot adequately be represented by a single structural formula but is a composite of two or more structures of higher energy.
- An example of a molecule which demonstrates resonance is ozone, O 3.

6 Physics A short-lived subatomic particle that is an excited state of a more stable particle.
- A statistical model for decay and formation of heavy hadronic resonances is formulated.
- The ρ meson is a wide resonance (Γρ = 150 MeV) and will decay primarily inside the nucleus, making it ideal for observing medium effects.
- The evidence for the new particle is a resonance observed when studying the invariant mass combinations of D*- anti-charmed mesons (dcbar) with protons (uud) and the anti-matter equivalent, D*+ mesons with anti-protons.
Late Middle English: from Old French, from Latin resonantia 'echo', from resonare 'resound' (see resonant).
