In physics, resonance is the tendency of a system to oscillate at maximum amplitude at certain frequencies, known as the system's resonance frequencies (or resonant frequencies).
this are common examples of resonance:
One familiar example is a playground swing, which acts as a pendulum. Pushing a person in a swing in time with the natural interval of the swing (its resonance frequency) will make the swing go higher and higher (maximum amplitude), while attempts to push the swing at a faster or slower tempo will result in smaller arcs. This is because the energy of the person pushing the swing is maximized when the pushes are at the resonance frequency, while some of this energy is canceled out by the inertial energy of the swing when they are not.
Resonance occurs widely in nature, and is exploited in many man-made devices. Many sounds we hear, such as when hard objects of metal, glass, or wood are struck, are caused by brief resonant vibrations in the object. Light and other short wavelength electromagnetic radiation is produced by resonance on an atomic scale, such as electrons in atoms.
Other examples are:
1. acoustic resonances of Musical Instruments and our vocal cords
2. the oscillations of the balance wheel in a mechanical watch
3. the tidal resonance of the Bay of Fundy
4. orbital resonance as exemplified by some moons of the solar system's gas giants
5. the resonance of the basilar membrane in the cochlea of the ear, which enables people to distinguish different frequencies or tones in the sounds they hear.
6. electrical resonance of tuned circuits in radios that allow
individual stations to be picked up
7. creation of coherent light by optical resonance in a laser cavity
8. the shattering of crystal glasses when exposed to a musical tone of the right pitch (its resonance frequency).

Resonance is a phenomenon that occurs when an object or system vibrates at its natural frequency in response to an external force. This force can amplify the vibrations, resulting in a large amplitude of oscillation. An example of resonance is when a singer shatters a glass by singing at its resonant frequency, causing the glass to vibrate intensely and eventually break.
The condition is called resonance. Resonance occurs when a molecule can be accurately represented by more than one Lewis structure, where the actual structure is a hybrid of the different resonance forms.
CO2 and SF4 exhibit resonance because they both have multiple resonance structures due to the presence of multiple double bonds. BH3 and NH3 do not exhibit resonance as they are both stable molecules with no additional resonance structures.
Yes, CH3NH2 can have a resonance structure. The lone pair on the nitrogen can delocalize to form a double bond with the carbon, resulting in resonance stabilization.
Resonance. Resonance occurs when multiple Lewis structures can be drawn to represent the same molecule or ion, indicating that the actual structure is an average of the different resonance forms.
Magnetic Resonance in Chemistry, a scientific journal focusing on magnetic resonance techniques in the field of chemistry, was first published in 1969. It has since become a respected source for research in the field of NMR and MRI applications in chemistry.
No, nitrate (NO3-) is not an example of an ion that forms resonance structures. Nitrate has a stable structure with a formal charge distributed over all the atoms in the ion, and it does not exhibit resonance.
Resonance
Ozone is not an example of resonance (by all possible meanings). It does have two bonding forms that it occasionally changes between. These two forms are called resonant states... but the bonding does not "resonate" per se.
The piano, guitar, harp, violin, etc.
Resonance describes a 'condition' rather than a 'purpose', but it is made use of in (for example) radio circuits, in order to tune the radio to a particular frequency (the resonant frequency of the signal).
I'll not give you the top 10, but:- Lead, or other soft metals such as gold, will have a poor resonance, for the crystal structure will not sustain resonance - the energy is absorbed in the metal. Conversely, brittle metals such as tungsten will have better resonance. But are too expensive for consideration. Bronze, a combination of copper and tin is commonly used for bells, as is brass for small bells. But heat treatment will change these characteristics. For example the steel drum bands of the Caribbean, where heat treatment and judicious stretching can produce a wonderfully resonant material.

Resonance refers to the phenomenon where an object vibrating at a certain frequency can cause another object to vibrate at the same frequency. An example of resonance is when a singer hits the right note that shatters a wine glass due to the glass vibrating at the same frequency. Another example is the Tacoma Narrows Bridge collapsing due to wind-induced vibrations matching the bridge's natural frequency.
