A tuning fork is an acoustic resonator in the manifestation of an a few-pronged fork with the prongs (tines) shaped from a U-shaped bar of flexible metal (as a rule steel). It resounds at a particular reliable pitch when set vibrating by striking it in opposition to a surface or with an item, and emanates an immaculate musical tone following holding up an instant to permit some heightened suggestions to cease to exist. The pitch that a specific tuning fork produces hinges on the length of the several prongs. Its principle utilize is as a standard of pitch to tune different musical instruments.

The "tuning fork" was created by John Shore, English musician to the regal court in 1711 and had a pitch of A423.5. The numbers underneath the musical notes stand for the Hertz (Hz) or cycles for each second of the quality wave made when the fork is vibrating.

A tuning fork serves as a suitable outline of how a vibrating question. When the tuning fork is hit with an elastic pound, the tines start to vibrate. The over and over again vibration of the tines process aggravations of surrounding breeze particles. As a tine extends outward from its common position, it packs surrounding breeze particles into a modest locale of space; this makes an elevated force area following to the tine. As the tine then moves internal from its typical position, atmosphere surrounding the tine broadens; this produces a flat force locale following to the tine. The heightened force districts are regarded as compressions and the flat force districts are reputed to be rarefactions. As the tines keep on to vibrate, a rotating plan of high and level force areas are made. These districts are transported through the surrounding breeze, moving the intonation indicator from one area to a different one.
