Imagine a world where sound becomes visible. In a room full of conversation, we would see soundwaves flowing from person to ...

A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...

Researchers discover collisionless shock waves as cosmic engines accelerating subatomic particles in space to extreme speeds.

In a groundbreaking experiment, researchers at Imperial College London's Department of Physics have uncovered a surprising ...

Pressure changes can be plotted on a waveform, which highlights the air particles being compressed and rarefied, creating sound waves that spread outwards. A tuning fork being struck can provide an ...

So far, cloaking has only been studied with waves—such as light or sound waves ... The research team lets small particles, so-called colloids, flow in a magnetic field of a checkerboard pattern.
