In a pulsed wave transducer the speed of sound in PZT and the frequency of sound are _____ related.

Explanation:
The emitted frequency in a pulsed-wave transducer is set by the crystal’s thickness and how fast sound travels in the crystal. For a plate that resonates in its thickness mode, the fundamental frequency is f = v/(2d). With the crystal thickness fixed, increasing the speed of sound v makes the frequency increase in direct proportion. So, the speed of sound in PZT and the frequency of sound are directly related. The other ideas don’t fit because an inverse or exponential relationship isn’t what the resonance condition predicts, and saying they’re unrelated ignores the clear link between material properties and the resonant frequency.
