Cymatics (from Greek: κῦμα wave) is the study of visible sound co vibration, a subset of modal phenomena. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid.[1] Different patterns emerge in the excitatory medium depending on the geometry of the plate and the driving frequency. The apparatus employed can be simple, such as the old Chinese spouting bowl, or Chinese singing fountain, in which copper handles are rubbed and cause the copper bottom elements to vibrate.[citation needed] Other examples include the Chladni Plate[2] and the CymaScope. The generic term for this field of science is the study of modal phenomena, retitled Cymatics by Hans Jenny, a Swiss medical doctor and a pioneer in this field. The word Cymatics derives from the Greek kyma meaning billow or wave, to describe the periodic effects that sound and vibration have on matter. youtube/watch?v=cbDn1qvU81c
