"VWR"

An exciting, interactive exploration, this generator includes various mass attachments to investigate degrees of string tension in standing waves.

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.

Bring your physics equipment into the 21st century with the new CENCO complete pendulum set.

Bring your physics equipment into the 21st century with the new and improved CENCO physics acoustic resonance apparatus.

Used to investigate wavelength in air.

Reliable and User Friendly

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

Lower Frequency Than Traditional Forks

Experiment With Sound Wave Interference

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

A must for your optics lab!

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

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

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

A mess proof way to demonstrate waves and refraction in water.

The demonstrations feature the fundamentals of vacuum and air pressure as they describe how a pump works and how to find the mass and density of an air sample.
