Can someone please tell me what the purpose of the quarter wavelength theory is? Why is it not 1/8 wavelength or even 1/9th . Why does it have to be 1/4? is there any justification/explanation. I understand it's for better acoustic matching but does ithave to be 1/4 for optimum matching?
Thanks
Thanks to all the valauble contributors in this website.

To my question ---> I would like to know why clamp-on ultrasonic transducers (the ones that are used for flow measurment in pipes) come with a piezo crystal on a wedge instead of directly mounting it on to the...
Hi guys,
Firstly, thanks to everyone for this wonderful forum. It's a great source of help.
To my question. I am trying to calculate the natural frequency of a piezo electric crytal I have. It's 10mm in diameter and 1 mm in thickness. Could someone please tell me which equation I'd have to use...
