These long-lasting aluminum tuning forks have a full sound.

Simple Mechanical System Clearly Conveys Complex Physics Principles.

The Large Wave form helix easily demonstrates wave phenomena.

Long, pure sounding aluminum tuning forks.

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.

Designed for Physics and Physical Science experimentation.

This self-contained apparatus explores wave velocity.

High power and versatility.

Equilateral prisms, made from high quality clear acrylic sheet.

Both versions of these economy tuning fork sets come with a mallet designed for one hard and one soft end for use with all frequencies of forks.
