A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

Students learn how sound waves are produced and transmitted. Students learn how sound waves are produced and transmitted and how frequency is related to pitch. The speeds of sound in different media ...

Sound has negative mass, and all around you it's drifting up, up and away — albeit very slowly. That's the conclusion of a paper submitted on July 23 to the preprint journal arXiv, and it shatters the ...

Yale scientists used laser light to gain access to long-lived sound waves in crystalline solids as the basis for information storage. The result was published online April 2 in the journal Nature ...

Sound has a speed limit. Under normal circumstances, its waves can travel no faster than about 36 kilometers per second, physicists propose October 9 in Science Advances. Sound zips along at different ...

A new type of extinguisher that uses sound waves to put out fires has been built by two engineering students in the US. Both chemical- and water-free, the invention offers a relatively non-destructive ...

The film "LearningAboutSound" explores the science of sound, detailing how vibrations create sound waves that travel through different mediums like air, water, and solids. It explains key concepts ...
