Sound waves can reflect off surfaces ... High frequency ultrasound waves can be used to detect objects in deep water and to measure the depth of the sea. Ultrasound is reflected off an object ...

sound waves cause air particles to vibrate back and forth ripples cause water particles to vibrate up and down Waves cause a disturbance of the medium through which they travel. This allows them ...

shows how an innovative and non-toxic process using ultrasonic sound waves can alter the surface of glass, making it either hydrophobic (water resistant) or electrically charged. Lead researcher ...

Sound waves may be the energy of the future since they are 14 times more potent than hydrogen. They could boost production of ...

“Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection of the density ripples that go along with it,” lead author Martin Zwierlein ...

Researchers manipulated water waves to move ping pong balls with a level of precision that seems straight out of a sci-fi movie.

"The sound waves create microscopic bubbles in a diazonium ... making it either permanently water-repellent or positively charged, depending on the type of diazonium salt used.

The technique to shape water waves was developed through an interdisciplinary effort inspired by Asst Prof Shen's prior work -- using light waves to create complex structures or patterns of light.
