"Sound" is a mechanical wave traveling through a medium. Ultrasound is sound, but its frequency is higher than humans can hear.
what are the similarity between aim objective
the similarity between sports and games are that there really entertaining, enjoyable and fun. you learn better.
The only similarity which I identified between these programs is of "HUMAN INTERACTION"
which of the following describes the similarity between the retained earning, and common stock account?
long
Infrasound has a longer wavelength.
Ultrasound is above 18 kilohertz. Infrasound is below 20 hertz.
Infrasound has a frequency below normal hearing. Ultrasound waves have a frequency above the normal range of human hearing.
Infrasound is always smaller or lighter than ultrasound. For example: infrasound can be the sound of a paper clip hitting the floor, and ultrasound can be the sound of two planets colliding.
No, but you can use ultrasound to clean glassware.
The opposite of ultrasound (above the human hearing range) is infrasound (below the human hearing range).
Acoustics is the study of sound, ultrasound and infrasound, that is, waves in gases, liquids, and solids.
Sonic infrasound is a sound too low for humans to hear, below 20 Hertz. Ultrasound is a sound too high for humans to hear, above 20,000 Hertz.
Infrasound is sound that is lower in frequency than 20 Hz (Hertz) or cycles per second, the normal limit of human hearing. Ultrasonic waves have frequencies above the audible range at around 20 kHz. Audible sound is within human hearing range.
I beg your pardon? Sound is not a person, let alone a living being. >:-(
Humans can't hear sounds that are below 20Hz (infrasound) or above 20,000Hz (ultrasound). Infrasound is produced by natural phenomena like earthquakes and by some animals, while ultrasound is used in medical imaging and by animals like bats for echolocation.
Sound too low in frequency to hear (~<20Hz) is called infrasound. Sound too high infrequency to hear (~>20kHz) is called ultrasound.
