Cymatic Patterns


Ripple2.jpg


Cymatics, from Greek: κῦμα, meaning "wave", is a subset of modal vibrational phenomena. The term was coined by Hans Jenny (1904-1972), a Swiss follower of the philosophical school known as anthroposophy. 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. Different patterns emerge in the excitatory medium depending on the geometry of the plate and the driving frequency.

I became very interested in the cymatic patterns visualized trough the vibrations in water, it intrigued me that water, a transparent fluid, can create such patterns and can actually exhibit an image. The pattern it makes communicates something about sound waves and displays a beautiful interaction between them.


Ripple Tank

A ripple tank is a shallow glass tank of water used in schools and colleges to demonstrate the basic properties of waves.

Interference

Ripple tank with source1 and source 2 interference in white and black visualization Interference can be produced by the use of two dippers that are attached to the main ripple bar. Notice the grey areas: they are areas of destructive interference where the waves from the two sources cancel one another out.
