Tuning fork

A tuning fork is a simple yet ingenious device that produces a precise pitch when struck. Its design typically consists of a U-shaped metal structure that vibrates at a specific frequency, providing a standard reference for musical notes or sound frequencies. The most common tuning fork resonates at the frequency of 440 Hz, which corresponds to the musical note "A" above middle C. Musicians often use this tool to ensure their instruments are in tune before a performance, as it helps them achieve harmony and accuracy in their music. Additionally, tuning forks are utilized in various scientific applications, including sound experiments and therapeutic practices, such as sound healing. Overall, the tuning fork remains an essential tool in both musical and scientific fields due to its reliability and precision.
