Tuning Fork EXPLAINED
As soon as this guy taps the metal with a hammer, it starts vibrating back and forth, and it’s kind of mesmerizing to watch. And while it may look like the arms are moving in slow motion, that’s actually because they’re vibrating so fast that the camera can’t keep up, creating this cool visual effect. This is called a tuning fork, and when you strike it, its two arms vibrate together to produce a sound. The pitch of this sound depends on the fork’s size and material, meaning each fork creates a specific note. They were originally used to tune instruments in the 1700s, but now they’re used in meditation and sound therapy
