So-called Rayleigh–Bloch waves can release an enormous amount of energy that can damage technical systems under certain circumstances. They only exist below a precisely defined cut-off frequency ...

(NASA via AP) NEW YORK (AP) — Scientists have detected cosmic waves that sound like birds chirping in an unexpected place. These bursts of plasma, called chorus waves, ripple at the same frequency as ...

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 ...
