A tuning fork, formed of a two-pronged fork, is an acoustic resonator with prongs formed from a U-shaped bar of elastic metal.

The length of the prongs determines the particular pitch of the fork. Most of the time it is used as a standard of pitch to tune other musical instruments. In 1711, John Shore invented the tuning fork. The...
