I need to design an experiment to find the resonant frequency of porcelain.

i'd appreciate any suggstions.

 

(or the answer; i don't need to design the experiment if someone has the answer)

Porcelain does not have a single resonant frequency; different objects made of porcelain will have different resonances, and may actually have multiple resonances.

 

A simple test is to place a microphone next to the object and tap it with a small mallet. You'll see the resonant frequencies in the recording of the "thonk" noise as the object vibrates after it's been hit.

thank you

Alternately you can subject it to different frequencies and see which ones are attenuated or not.

Here's a cool example, but without the analysis part
