Unit consists of a sturdy metal frame carrying a DC motor with an eccentric shaft for exciting the vibrations. Clamp the frame to a table, attach a string and then simply use masses and a pulley to put tension on the string.

Long, pure sounding aluminum tuning forks.

Introduce students to different standing waves.

This box shows Planck's Constant in action.

Both of these sets come with a roll-up style canvas storage pouch and a solid rubber activator.

These large alloy tuning forks are designed to demonstrate resonance, beat frequency, and sympathetic vibration.

Scientific tuning forks are designed for acoustic research, sound wave analysis, and calibration standards.

Get students into the swing of things with the Doppler effect.

This compact tank can be used on an overhead projector or as a traditional ripple tank.

Amaze your students with this physical science kit that teaches an inquiry-based lesson on forces.

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.

Provides electronically controlled waves.

Stroboscope light synchronizes with ripple generator.

Determine the speed of sound in air by investigating the resonance of a column of air.

This ripple tank is transparent, acrylic plastic and supported in a sturdy plastic frame.

Explore a standing wave on a string and determine the linear mass density of the string.
