PZT thickness and frequency are related how?

Explanation:
In a PZT transducer operating in thickness mode, the plate supports a standing wave whose thickness corresponds to half a wavelength. The material’s sound velocity is basically fixed, so the fundamental relationship is f = v/(2t). This means the resonant frequency is inversely proportional to the thickness: thinner plates resonate at higher frequencies, thicker plates at lower frequencies. This inverse relation is the key concept.
