Fantastic, thank you very much!

Hello People! So currently I have an AC input going into a capacitor and inductor in parallel, and I want the output from the capacitor and inductor to go into a switch that flips from outputting the capacitive load's output and the inductor's load output, a little diagram is shown below...

Hello Physics Forum people! I am working on a project involving indoor mapping, and I have just received 10 SRF02 ultrasonic range finders to hook up in an array to measure distances using sound waves and use this data to map out buildings. However, we are looking to receive the "raw signal...

I assume it would cause a compression where the force is applied and an expansion just about everywhere else, most significantly at the opposite side of the force

So, let's imagine we have a sphere of metal with a piezoelectric film all around the outside of it. If we applied a point force to one area of the sphere, how would the piezoelectric material react? Would it compress or expand at that point, and how can we measure the force based on the response...

Here is the URL for the instructables page: http://www.instructables.com/id/Birth-of-Man-Mixing-Board/ Thank you for all you're help

The schematic was off of instructables.com but it's just not working with the dual op amp. If I made the circuit that @Baluncore made would it be able to work? Thanks for all the help it really is great.

Sorry for all the extra pictures my computer was being weird.

Hi all, I am making a frequency mixer to add together channels of an amplifier I have at 52.892kHz. I am attaching a picture of the schematic and the physical circuit I made along with the output on the oscilloscope I am measuring. Instead of the three outputs shown in the schematic, I am just...

Yes

Forgot to attach the picture, here it is:

So I am looking to possibly use a ring transducer that has a hoop vibration mode to power a sonoluminescence experiment I am doing for school. I am attaching a picture of the set-up I have now and the aluminum disc in the picture is where I will epoxy the transducer so it can send sound waves...

Hello everyone! I previously opened a thread asking about sound wave energy loss in aluminum discs based on thickness. I am looking to find out more about exactly how much using a disc that is twice the thickness of the other, (one is 1/8" and the other is 1/4") sound energy would be lost using...

Thank you very much for all of your help. That answer helps with everything!

The geometry of the glass is an outside diameter of 100mm, wall thickness of 5mm and a length of 415mm. The desired frequency is 40kHz approximately but we will be working in a range between 20-60kHz. The sound waves are to propogate in the water.
