An ultrasonic wave is a sound wave vibrating at a frequency beyond the human hearing. The wave is emited from a devise (or an organ in the case of animals such as bats). The wave then hits an object and reflects of it (an echo). The devise (or another organ in the bat) will detect the reflect wave and measure its direction and the time it took to be reflected and the devise would use that information to produce an image.
It works pretty much like our ability to see. Light hits objects and is reflected off them and hits our eyes. An ultrasonic devise "sees with sound" waves instead of light waves.
During pregnancy, a devise omits an ultrasonic wave (you can't hear it!) The wave will hit many things in the stomach but the devise is programmed so that it only measures a specific distance (or time) which is to the fetus. The sound waves hit the fetus and bounce back.
hope this helps
Yes
Yes, Ultrasonic liposuction does work wonders for people with a lot of weight to lose. It is very safe and effective and does not have any serious complications.
Not as far as I'm concerned.
None of them work long term for anything.
i dont really know
Ultrasonic sensors are also known as transceivers but are more generally called transducers. Ultrasonic sensors work similar to radar or sonar which generate high frequency sound waves.
The best degreaser to use for an ultrasonic cleaner is a specialized ultrasonic cleaning solution that is designed to effectively remove grease and grime from various surfaces. These solutions are formulated to work efficiently with the ultrasonic cleaning process, providing optimal results.

An ultrasonic jewelry cleaner works by using cleaning fluid in a container to clean jewelry. A motor device creates ultrasonic waves which travel easily through the cleaning solution. These waves work to dislodge dirt and grime from the jewelry item in as little as 3 minutes. Longer may be required for large pieces or those with more dirt.
No, ultrasonic mosquito repellers do not work. Extensive tests have been run on them. The facts is, mosquitoes don't even have ears. ... i agree they dont work but mosquitoes can defenetly hear. they dont have ears as such but they have complex hearing organs.
Ultrasonic humidifiers use high-frequency vibrations to create a fine mist of water droplets, which are then released into the air to increase humidity levels in a room.
