Most of us are used to experiencing sound as an exclusively auditory experience. But scientist and photography enthusiast Linden Gledhill isn’t most of us. He sees it. And he’s happy to show how. The Philadelphia-based pharmaceutical biochemist has been playing with cymatics for a few years now, and he’s come a long way.
“The equipment [that I use] is very simple,” Gledhill told Bored Panda. “[It consists of] a stretch membrane over a speaker, holding a pool of water which is oscillated with specific frequencies from an amplifier driven by a virtual tone generator. The surface of the water is lit with LED lights and images are captured with a camera.”
“Basically, when liquid is vibrated in a confined space it results in standing waves at specific frequencies,” he explained. “These are known as Faraday waves (nonlinear standing waves that appear on liquids enclosed by a vibrating receptacle). This is similar to how specific notes form in musical instruments.”
“The sound is passed through the water and the vibrations are imprinted on the surface which reflects the LED lights. The camera images the light reflected off the surface. The patterns and shapes…
