Ultrasound is an ultrasonic wave that is higher freguency than the audible
frequency (16 ~ 20kHz) and can not be heard by human.
The number of times a point in the medium vibrates for 1 second during
the course of the wave, in Hz.
The higher the frequency, the faster the ultrasound is absorbed.
Overall, frequencies from 0.5 to 1 MHz are used for deep tissue and high
frequencies (2-3 MHz) are used in the skin and subcutaneous tissue.
When the wave is periodically observed repeatedly while the flow of time
is stopped, the distance between the crests and the bone crests is called the
wavelength. Propagation speed and wavelength vary depending on the material.
