The highest pitch of a tuning fork is?

The highest pitch of a tuning fork is determined by its frequency, which is measured in hertz (Hz). Tuning Forks come in various sizes and can be designed to produce different pitches, with smaller forks typically generating higher pitches. For example, a standard A440 tuning fork vibrates at 440 Hz, while smaller forks can reach frequencies above 1000 Hz. The specific highest pitch would depend on the design and purpose of the tuning fork in question.
