Produces circular waves from either one or two point sources. The phase relationship is continuously adjustable. A variable, low voltage power supply, such as our 64250-10, allows the speed to be adjusted also. Securely mounted in a molded housing with four non-skid, shock-absorbing feet.

• Includes two point sources for generating circular waves, and ripple bar for generating straight waves
• Includes instructions
• Phase control, with variable amplitude and frequency, for varying interference patterns
