sound wave

Because a fish's body is close in density to water, sound waves pass through it.

While the molds use chemical signals to coordinate, Aronson and his collaborators chose acoustic communication instead, since sound waves travel faster than chemical signals, making the approach more practical for robotic applications.

Sonar imaging, which mapped the ocean floor using sound waves, led researchers to what they claimed was a small aircraft.

Lossless works by capturing the recording’s original sound waves and putting them together to create an accurate reproduction of its initial quality.

With their headphones on, they bobbed their heads to the beats they were cooking up and watched intently as sound waves danced across their laptop screens.
