WebUltrasound Terminology. Period is the time for a sound wave to complete one cycle; the period unit of measure is the microsecond (µs).Wavelength is the length of space over which one cycle occurs; it is equal to the travel distance from the beginning to the end of one cycle.Frequency is the number of cycles repeated per second and measured in hertz (Hz). Web26 Dec 2015 · Ultrasound, as the name implies, is high-frequency sound. Sound waves travel through a medium by causing local displacement of particles within the medium; however, there is no overall movement of the medium. Unlike light, sound cannot travel through a vacuum as sound waves need a supporting medium. Consider a piece of string held at … sprouted rolled oats recipes
