What is the difference between the sound waves and ultrasound?

Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit


What is a sound with frequency greater than 20000 hz?

the sound would be called "ultrasound"


What are related words for ultrasonic?

How ultrasound and infrasound differ from normal sound?

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.


What is the difference between infrasound and ultrasound And provide one example of how each is used?

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.

What is the ultrasound principle in Doppler ultrasonography?

The ultrasound principle is this: when a high-frequency sound is produced and aimed at a target, it will be reflected by its target and the reflected sound can be detected back at its origin.


When do you have an ultra sound?

Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. This frequency varies from person to person, it is approximately 20 kilohertz (20,000 hertz). This is the lower limit in describing ultrasound.
