Closely wound steel helix for studying wave behavior.

Create waves and signals quickly and easily.

Used to investigate wavelength in air.

Lower Frequency Than Traditional Forks

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

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

Observe phase reversal at the fixed end of wave pulses with this spring used to test waves in fundamental and multiple vibrations.

Make sound measurements with greater precision and convenience.

Two sets of popular tuning forks are available.

Used for auditory responses. Available with or without fixed weights.

A Classic Demonstration!

This bell jar demonstrates that sound waves can't travel and therefore can't be heard without air or matter.

This set provides versatile tools for a variety of demonstrations.

Boomwackers are brighly colored plastic tubes tuned by length to musical notes.

Multi-purpose drilled ball set ideal for pendulum experiments but can be used to meet a variety of lab needs.
