What term describes the vibrations that create sound?

The term that describes the vibrations that create sound is "sound." Sound is generated when an object vibrates, causing surrounding air (or another medium) to vibrate as well. These vibrations travel as waves, which we perceive as sound when they reach our ears. Understanding this concept is fundamental in physics, as it demonstrates the physical nature of sound production and transmission, linking it closely to the properties of waves and vibrations.

While the other terms relate to different concepts—light pertains to electromagnetic radiation, motion refers to the movement of objects, and color is associated with the visual perception of light—none of these terms accurately describes the specific process of creating sound through vibration.
