PIEZOELECTRIC EFFECT -- PRODUCTION OF ULTASONIC WAVES

When an AC Voltage is applied across a piezoelectric crystal such as Quartz Crystal, It vibrates at the frequency of the applied voltage. Vibration of maximum amplitude occurs at the natural resonant frequency of the crystal which is determined by physical dimension and by the way the crystal is cut. The Frequency is given by ...
