Water, sand, and carbon dioxide-based fire ... Using an air vortex cannon to focus the sound waves from the bass reflex port, it ‘wiggles’ the flame out in a matter of seconds, as illustrated ...

A group of international researchers have developed a way to use sound to generate different types of wave patterns on the surface of water and use those patterns to precisely control and steer ...

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 ...

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 ...

Researchers have now developed a method that prevents sound waves from travelling backwards without deteriorating their propagation in the forward direction. In the future, this method could also be ...

This experiment demonstrates how water affects sound waves and pitch. You'll discover how different water levels create different musical notes and learn about the relationship between mass, vibration ...

In the guest blog, physicist Andrea Navarro-Quezada shows the importance of sound waves for our everyday life and research. Almost all of us know the concept of a wave. It is a periodic motion or ...

JFontan – stock.adobe.com Sound is more than just noise — it’s made up of mechanical waves that create tiny vibrations traveling through the air, water or even tissue. We’ve long known ...

These devices generate vibrations in the ultrasonic range, which spread through the brain as waves. At certain points in the brain, the waves emitted by two or more transducers can either amplify each ...

It’s because space doesn’t carry sound in the way we experience it on Earth. There is no air or water to carry pressure waves that create audible sound. But that does not mean the universe is ...
