It does not necessarily need to be ultrasound but I was under the impression that it would work better. What do you mean by matching my power into the glass?

Basically, I want to move water on the other side of the glass using sound. I'd rather not give out any more details about the why.

I think that's hard to explain. It's probably moving with the plate, but if you look at the water compared to the glass, its location doesn't seem to be changing.

That actually helps quite a bit. Thanks! I believe this is off topic, but I'm not just doing this to learn. It's not just a random thing I decided to do. I have an end goal in mind with what I'm doing with this. The science behind the signal propagating through water just isn't quite what I...

The sheet of glass rotates, but the water seems to remain stationary on the glass. If the glass is held in place, there's no movement in the water.

Yes. Or visibly move in some way.

I was expecting some kind of movement in the water. The glass noticeably moves. I tried the same experiment with a piece of paper with crumbs on it and the crumbs moved, as well as the paper when I stepped up the voltage. Edit: I'm afraid I don't know much about how the sound/vibrations work...

I'm trying. I thought I was pretty clear. The water (a few drops) is just directly on top of the glass, which is laying flat, which is directly on top of the transducer. There's nothing else involved other than my circuit to power it. Edit: What else do you need to know? The glass is 3.5mm...

I have a thin sheet of glass sitting on top of the ultrasonic transducer. The water is on top of the glass. I have a 40kHz signal around 120V peak to peak

Not sure if I'm putting this in the right place, but here's my issue: I'm putting a ultrasonic transducer against glass to try to vibrate/move water on the other side of the glass. I can get enough power through the transducer to physically move the glass, yet I still can't get water to move...
