A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs formed from a U-shaped bar of elastic metal (usually steel). It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object, and emits a pure musical tone once the high overtones fade out.
Over time, tuning forks were adapted for use in medical and therapeutic settings, where their precise frequencies have been harnessed for healing and therapeutic purposes. [ 3 ] Tuning forks are known for their nearly pure frequency response, emitting a clear, unwavering tone that is free from the complex overtones found in other instruments.
When one fork is struck and held near the other, vibrations are induced in the unstruck fork, even though there is no physical contact between them. In similar fashion, strings will respond to the vibrations of a tuning fork when sufficient harmonic relations exist between them.
Experiment using two tuning forks oscillating at the same frequency.One of the forks is being hit with a rubberized mallet. Although the first tuning fork hasn't been hit, the other fork is visibly excited due to the oscillation caused by the periodic change in the pressure and density of the air by hitting the other fork, creating an acoustic resonance between the forks.
