vibrating strings

Vibrating strings produce sound when they oscillate, creating waves along their length. When a string is plucked, struck, or bowed, it moves back and forth rapidly, generating mechanical vibrations. These vibrations cause air particles nearby to move, creating sound waves that travel to our ears. The pitch of the sound depends on the string’s length, tension, and mass; shorter, tighter, or thinner strings vibrate faster, producing higher tones. This principle underlies instruments like guitars, violins, and pianos, where controlling these factors alters the sound’s pitch and quality.
