A new University of Mississippi study shows that some sound waves don't just move forward—they also move slightly to the side. Understanding this movement could help researchers develop more precise ...

Former elementary school teacher Matt Shurtleff — known to many students as “Matt the Mad Scientist” — demonstrated how sound waves move using water and lasers.

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 ...

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...

Why the sun's corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A 'hot' trail to explain this effect leads to a region of the solar ...

At the start of my career, I used to do acoustic testing in an anechoic chamber where sound is not reflected as it gets absorbed. But the quietness of these chambers always got me thinking of how ...
