Ultra Sound
Ultrasound cannot be heard as it has a higher frequency than audible sound, with a frequency above 20000Hz.
A person who uses sound waves to make images of the body is known as a sonographer or ultrasound technician. They operate ultrasound machines to capture images of internal organs and tissues for diagnostic purposes.
ultrasound
The wavelength of ultrasound can be calculated using the formula: wavelength = speed of sound / frequency. Assuming the speed of sound in human tissue is about 1540 m/s, the wavelength of 3.5 MHz ultrasound would be approximately 0.44 mm.
The definition of Ultrasound is very short wavelengths of sound used in a similar way to x-rays. The reason that ultrasound is used is the fact that sound does can be used for getting moving pictures of internal bits of the body that x-rays can show as accurately
Just to give some clarity, ultrasound doesn't travel faster than sound. It simply resonates at a higher frequency than normal sound. Sound in a lighter atmosphere, or light travels faster than ultrasound.
Ultrasound
Infrasound refers to sound waves with frequencies below the range of human hearing (below 20 Hz), while ultrasound refers to sound waves with frequencies above the range of human hearing (above 20 kHz). Infrasound is used in monitoring seismic activity and animal communication, while ultrasound is used in medical imaging, industrial cleaning, and pest control.
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.
because ultrasound is more safer than audible sound.
Sound below 20Hz is considered infrasound, while ultrasound typically refers to sound frequencies above the human hearing range (above 20kHz).
You can't produce ultra-sound from a normal speaker. There would be no current to drive the coil due to the high frequency. It would have to be an ultrasound transducer.
Infrasound has a frequency below normal hearing. Ultrasound waves have a frequency above the normal range of human hearing.
Ultra Sound
Ultrasound is typically performed by a trained ultrasound technologist, it involves using sound waves to get an image of the reproductive system.
"Sound" is a mechanical wave traveling through a medium. Ultrasound is sound, but its frequency is higher than humans can hear.
