Ultrasound is above 18 kilohertz.
Infrasound is below 20 hertz.
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 has a longer wavelength.
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.
"Sound" is a mechanical wave traveling through a medium. Ultrasound is sound, but its frequency is higher than humans can hear.
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.
The difference between ultraviolet radiation and ultrasound is how they react when inside the body. Ultraviolet radiation attacks the cells and destroys cells that are harmful to the body. Ultrasound is merely a viewing device. Ultrasound is used to detect abnormalities in the body.
Ultrasound.
I beg your pardon? Sound is not a person, let alone a living being. >:-(
