Hello! My name is Nick and I have an MSc in Computer Science, I'm also Physics enthusiast and amateur/independent researcher. I would like to ask for your help on something. I'm currently trying to find a way to study ultrasonic waves' effects on water and I'd like to find a means of transferring a specific frequency (that would be 600 khz) to water. Unfortunately I was not able to find a cheap ultrasonic transducer working at that high frequency. The ones I found start from many hundreds of $. The wave type I'm trying to transfer is longitudinal waves (like sound waves), not transverse waves. So I was thinking of like a metallic tank, on which I would apply the transducer and that would transfer the waves to the water. Another way I thought of to produce this kind of waves at that high frequency is by making a custom siren type generator. But based on my calculations, this is also difficult because I'd need a siren with around 370 holes on every disc, spinning at 10.000rpm to produce only 60.000 and 600.000Hz would be the 10th harmonic. I was about to completely abandon the idea but I recently was told of a man who has succeeded in using a siren for the same job in the past and he was able to reach that high frequency. Unfortunately I don't have any way to contact him to ask, so I'm instead asking kindly for your help because this seems to be a dead end to me. I don't own or have access to any special kind of tools like laser cutters or anything like that but I would be able to use plexi glass for a custom made siren. Any thoughts please? :-)
