What is resonance give an example of resonance?

Answer 1

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.

Answer 2

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).
