The Power Amplifier is a very useful classroom resource that allows students to amplify and listen to a variety of audio sources ranging from microphones and audio devices with a 3.5mm headphone socket, to signal generators equipped with 4mm socket outputs. The amplifier is particularly suitable...
Intended for teacher demonstrations only. The Rubens' Tube is an Aluminium tube with a row of small holes drilled along the top and 10W loudspeaker mounted at one end. Full instructions included. Users will need a gas source (Natural or LPG) and a power signal generator to run the speaker.
The Vibration Generator gives mechanical oscillations when fed by signals from an oscillator/A.F. amplifier e.g. a Power Signal Generator. A special high temperature coil system enables the unit to be operated at its maximum rating for a prolonged period without damage due to overheating.

The Rubens’ Tube Pro is an exciting and very visual way to demonstrate the concept of a standing wave.
By making measurements it is also possible to calculate the speed of sound. The Rubens Tube Pro has a built-
in amplifier so it can be driven by a wide range of signal sources...
The ancestor of all cameras, this hand-held camera obscura projects an image onto a screen inside the box.
The wooden camera is supplied in kit form and has an authentic look and feel when assembled.
This compact unit provides an elegant method of demonstrating the wave phenomena of reflection, diffraction, refraction and interference with none of the setting-up problems usually associated with ripple tanks. The concept has been further developed to offer new features and simplicity in this ...
For demonstrating the production of beat frequencies. Comprises two nickel plated forks A (440 Hz) mounted on individual boxes. One fork is provided with adjustable mass by means of which frequency may be shifted from the nominal 440 Hz. When both forks are sounded a clearly audible 'beat...
