to create images of an unborn baby in a womb. A gel is placed between the ultrasound probe (transmitter/receiver unit) and the skin to allow ultrasound waves to be transmitted into and out of the ...
So, researchers developed a method to make sound waves travel in only one direction. The innovation has far-reaching applications that go beyond acoustics, such as radar. After years of research ...
A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...
Counter-intuitively, we also blow on a fire (or use bellows) to make it burn better ... Using an air vortex cannon to focus the sound waves from the bass reflex port, it ‘wiggles’ the flame ...
This research analyzes the future of topological insulators using soundwaves (acoustic insulators inside, soundwaves conductors on their surface). Disclaimer: AAAS and EurekAlert! are not ...
