This hands-on apparatus demonstrates transverse and longitudinal waves.

Long, pure sounding aluminum tuning forks.

Reliable and User Friendly

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

This set provides versatile tools for a variety of demonstrations.

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

Create waves and signals quickly and easily.

Closely wound steel helix for studying wave behavior.

Make sound measurements with greater precision and convenience.

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