Hey all! So all my life I have heard that sound is a type of wave. This seemed to make sense to me. Recently I have come across some information that has me second guessing such tradition knowledge.

In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

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.

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 ...

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 ...

It’s a question I’m sure was keeping you up at night: can you make an object spin with a sound wave? The answer, generally speaking, used to be no. Now, though, mechanical engineers have taken a look ...

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 ...

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 ...
