I want a very small hydrophone. sound in water is longitudinal. This is always depicted as a bunch of dots, the "top" of the wave is where the dots are closest. I assume there really is compression of the water in those spots. this would mean more ions at those points in salinated water. I guess this means better conductivity at those times. If I carefully space two wires with a voltage across them close together and immerse the ends, the wires facing the wavefront, would I see a current varying with the soundwave passing the wire- ends ?
Re: can you sense a sound wave in (salinated) water by electrical resistance
