"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.

Used to investigate wavelength in air.

Designed for Physics and Physical Science experimentation.

A Classic Demonstration!

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.

Lower Frequency Than Traditional Forks

Closely wound steel helix for studying wave behavior.
