![]() Dense metals like copper and steel vibrate with a crisp, high pitch. You can also adjust the pitch of a tuning fork by making it out of different materials. If someone ever finds a hammer big enough to hit it, the sound would most likely be too low to be heard by human ears. The largest tuning fork in the world, by the way, is a 45-foot (13.7-meter) sculpture in Berkeley, Calif. A loose string, on the other hand, takes longer to shudder back and forth, resulting in a lower tone. Without much room to wobble, a tight string vibrates quickly. It's the same principle as strings on a guitar. The smaller a tine, the less distance it has to move, and the faster it will be able to vibrate. To mimic the lowest key, on the other hand, it would only need to vibrate at 28 Hz.īut how do you adjust the speed at which a tuning fork vibrates? Well, first, you could adjust the length of your tuning fork. For instance, for a tuning fork to mimic the top key on a piano, it needs to vibrate at 4,000 Hz. ![]() The faster a tuning fork's frequency, the higher the pitch of the note it plays. The result is a steady collection of rarefactions and compressions that, together, form a sound wave. When the tines snap back toward each other, they suck surrounding air molecules apart, forming small, low-pressure areas known as rarefactions. ![]() When a tuning fork's tines are moving away from one another, it pushes surrounding air molecules together, forming small, high-pressure areas known as compressions. The way a tuning fork's vibrations interact with the surrounding air is what causes sound to form.
