PITTSBURGH (KDKA) - The universe is full of waves, and they are not all created equally. Some are mechanical, and others are electromagnetic, even though they are all energy! Not all waves are created ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Water, ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. When you purchase through links on our site, we may ...

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 ...

Traditional computer chips run on electricity, while the emerging photonic chips use light. Now, scientists at Harvard have demonstrated a new kind of chip that transmits data in the form of sound ...
