Two piezoelectric crystals made from the same material: The thicker crystal will make a pulsed transducer with a lower frequency. True or False?

• A. True
• B. False

Answer: (B)

The statement regarding two piezoelectric crystals being made from the same material indicates that their thickness directly influences the frequency of the sound waves they produce when utilized in a pulsed transducer. In general, the frequency of the acoustic wave produced by a piezoelectric crystal is inversely related to the thickness of the crystal. Thicker crystals vibrate at lower frequencies because they have more mass, which dampens their ability to oscillate quickly. Conversely, thinner crystals can vibrate more rapidly, producing higher frequency sound waves. Therefore, when two crystals are made from the same material but differ in thickness, the thicker one will indeed generate a lower frequency compared to the thinner one. Thus, the correct answer to the question is True, as a thicker piezoelectric crystal does result in a pulsed transducer that operates at a lower frequency.
