Sound is not a thing, but a disturbance of matter
In short: Most people think of sound as a physical object moving through the air. This video visualizes why that is a misconception, showing how sound actually travels as a series of microscopic disturbances.
Sound is classified as a longitudinal wave, which means it moves in the same direction as the particles it travels through. The video uses the analogy of a slinky to demonstrate how energy moves forward while the medium itself simply oscillates back and forth.
To see these invisible waves in action, the video features a Rubens' tube, a device that allows viewers to see sound as physical patterns in a gas. It also explores the biological mechanics of how the human ear captures these disturbances to create the sense of hearing.
