The film explores the nature of sound waves, demonstrating how sound travels as a wave through air, which acts as a medium. It illustrates sound generation using a loudspeaker, examines oscillation, ...

Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...

Check one, two; check one, two; is this thing on? Over on The Public Domain Review [Lucas Thompson] takes us for a spin through sound, as it was in Britain around and through the 1800s. The article ...

Researchers have uncovered a way to control material behavior using sound. In a study ...

On the rise. Signs of convection are seen in the motion of hot gas under the influence of a gravity-like acoustic force in a spherical glass container. The images were recorded 15, 40, and 140 ...

This experiment demonstrates how water affects sound waves and pitch. You'll discover how different water levels create different musical notes and learn about the relationship between mass, vibration ...

WALTON, Ind. — As AC/DC's "Back in Black" thumped through a speaker in Andrew Berryman's classroom recently, physics students saw the notes come alive through flames. They were watching a Rubens' Tube ...

Be it water, light or sound: waves usually propagate in the same way forwards as in the backward direction. As a consequence, when we are speaking to someone standing some distance away from us, that ...
