Explain the quartz crystal method for detection of ultrasonic wave. |
Answer» <p>Quartz crystal method: This method is based on the principle of Piezo-electric effect. When one pair of the opposite faces of a quartz crystal is exposed to the ultrasonic waves, the other pairs of opposite faces developed opposite charges. These charges are amplified and detected using an electronic circuit.</p> | |
