A solenoid valve on a timing circuit releases droplets of water, which fall into the mirrored tank below. I built this apparatus to study circular wave phenomena. A camera captures the wave patterns and their reflections, and a piezoelectric crystal registers the sound each droplet makes as it strikes the water's surface. I was inspired to create this project after reading about Pilot-Wave Hydrodynamics and the Entropy of Circular Waves, which was a neat introduction to geometric information theory.
I write about what the phenomenological significance of this experiment here.
