SALT LAKE CITY (KUTV) — Former elementary school teacher Matt Shurtleff — known to many students as “Matt the Mad Scientist” — demonstrated how sound waves move using water and lasers. Shurtleff, who ...

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, ...

Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has ...

Scientists have created a new kind of time crystal using sound waves to levitate tiny beads in mid-air. These particles interact in a one-sided, unbalanced way, breaking the usual rules of motion and ...

Futuristic control of structure in some materials is being made possible by a physics loophole.

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

Mechanical engineers have demonstrated a set of prototypes for manipulating particles and cells in a Petri dish using sound waves. The devices, known in the scientific community as 'acoustic tweezers, ...
