sound wave

Echoes in whale songs recorded by seismic instruments on the ocean floor reveal that the sound waves pass through layers of sediment and underlying rock.

Analyzing EEG data in this way is analogous to looking at the sound waves from an audio recording made on a bridge over a highway, explains Lawrence Ward, a cognitive neuroscientist at the University of British Columbia.

They power themselves using the vibrations of sound waves hitting them.

She proposed in 2017 that an analogous disturbance from a dark matter interaction might generate sound waves that could slightly warm the system.

At pressures millions of times that of Earth’s atmosphere, sound waves move faster and could surpass the limit.

Similarly a sound wave in air is reflected upon striking the surface of a body.

During a complete vibration of the fork, therefore, the sound wave moves four times the length of the air column.

Let the curve A represent the sound wave sent out by one tuning fork and B, that sent out by the other.

The result was that I saw a wave of compression, of the same sort as a sound-wave in air, move through the throng.

Now the actions and reactions between the air-particles in a sound wave are purely mechanical.
