Tuning fork vibrations displacing water. A tuning fork is a piece of metal designed to vibrate and produce a musical note when struck. The frequency of the vibration,the number of times it vibrates every second,is measured in Hertz. This tuning fork produces musical notes of 440 Hertz. This is a widely recognised definition of the musical note 'A',so the tuning fork is named A440. Tuning forks help to illustrate the nature of sound as simply the vibration of air at a frequency that is audible to the human ear. Tuning forks are used to help tune musical instruments | |
