Sound is mechanical wave created by a vibrating object and transmitted through a medium.

Its frequency is measured by Hertz (1 Hertz = one cycle/second). Audible sound (human ears): 20 - 20,000 Hz.

The transducer (probe) contains a special type of crystal called Piezoelectric Element

Ultrasound is generated by the conversion of electrical energy into mechanical energy and is detected by the reverse process called
