“Sound waves, in particular, offer distinct advantages, as they are biocompatible and harmless and their short wavelengths can penetrate a wide range of heterogeneous, opaque and absorbing media ...

The iconic tagline of the 1979 sci-fi film "Alien" tells us that "in space no one can hear you scream." This was based on the fact that space is a vacuum, a region devoid of any particles. Sound ...

Identify the features of a sound wave and learn about pitch, frequency, amplitude and loudness in this guide for KS3 Physics students aged 11-14 from BBC Bitesize.

This breakthrough sound wave director consists of a disk-shaped cavity with three equidistant ports for sending or receiving sound. When activated, sound from one port is only heard at a specific ...

Yes, sound can definitely produce heat. But you can’t cook food from yelling at it (sorry Gordon Ramsey). What we call sound is really a patterned, regular, ordered movement of individual particles.

To understand why there’s no sound in space, first consider how sound works. Sound is a wave of energy that moves through a solid, a liquid or a gas. Sound is a compression wave .

There just aren’t enough particles to bump into each other to transport the acoustic wave. If you want sound to move through space, you need a much louder source that operates over vast volumes.

Published in the journal Earth, Planets and Space, their results show sound wave disturbance patterns in unique 3D detail and provide new insights into how earthquakes generate these waves.. With ...

These particles emerge from the collective motion of quadrillions of atoms, much as a ‘stadium wave’ in a sports arena is due to the motion of thousands of individual fans.

Scientists call this behavior a material’s “second sound” (the first being ordinary sound via a density wave). Although this ...
