Black holes are some of the most mysterious objects in the universe, but what if we could recreate their physics in a lab?

Scientists have unlocked a previously unseen behavior of acoustic waves, opening up new possibilities for cutting-edge ...

Sound waves can reflect off surfaces ... but can it travel through a vacuum?A simple experiment will give us the answer. Connect an electric bell to a battery and switch. Close the switch and ...

You can't, right? Well, not with your eyes. But you can "see" with sound waves. See how it works below, then find out what sonar is used for.

Turbulence can also occur in sound waves that propagate chaotically in certain media, such as superfluid helium. In the 1970s, Soviet scientists proposed that turbulence occurs when sound waves ...

“Colleagues and I successfully tested this theory in sound waves a few years ago, but until this most recent experiment, it ...

This removes the carrier wave from the signal. What remains is the audio signal. Speaker The audio signal causes the radio speaker's diaphragm to vibrate, which creates sound waves. A sound wave ...

In the experiments, the material serves a double function, Bilal explains, by being a perfect sound vacuum and wave amplifier at the same time. "A flat band in a band structure is a very special ...
