"Ward's Phenomena"

The Large Wave form helix easily demonstrates wave phenomena.

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

A Classic Demonstration!

Used to investigate wavelength in air.

Designed for Physics and Physical Science experimentation.

Reliable and User Friendly

With the Resonance Apparatus, students investigate the effect of frequency on wavelength.

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.

Simple Mechanical System Clearly Conveys Complex Physics Principles.
