“In space no one can hear you scream.” If space were truly empty—an utter vacuum, devoid of any matter—then yes, the Alien ...

The table gives some examples. This is because the particles of gases are further apart than liquids or solids. Sound waves travel more slowly when particles are further apart. Back to top Can ...

New research suggests that sound waves can influence cellular activity, including stopping the development of fat.

Sound waves travel through different types of matter, including liquid water. Importantly, the movement of ocean water can ...

In a nutshell Sound waves can influence how cells behave, even affecting fat development. In lab experiments, exposing cells to common sound frequencies like a 440 Hz tone significantly altered gene ...

For example, when two ultrasound beams of slightly different frequencies overlap, such as 40 kHz and 39.5 kHz, a new sound wave is generated at the frequency difference of 0.5 kHz, or 500 Hz ...
