Physics

This vibration generator is a sturdy, user-friendly tool for providing electronically controlled waves. Ripples can be created for the study of wave motion. (Recommended for use with square wave generator). Dimensions: 140 mm, overall diameter: 114 mm. The amplitude is +/- 3 mm.

This wave machine, which comes in kit form and must be self-assembled, is designed to demonstrate the theory of waves. The kit comprises: transverse wave machine with 80 arms spaced on nylon line with detachable weights to provide an example of transverse wave propagation in which movements of the rods create the waves; Two loaded elastic cords to illustrate transverse wave motion; An extension spring with weights, for the propagation of both longitudinal and transverse waves; teacher's book which describes the experiments and gives detailed quantitative analysis.

A Slinky-type spring for wave demonstration, with a wooden storage stand. Stand helps protect the spring in storage and keep it in good condition. Closed Spring Dimensions (Dia. x L): 72 x 220 mm. Base Dimensions (L x W x H): 150 x 150 x 355 mm.

To demonstrate form and propagation of longitudinal and transverse waves. This simple wave demonstrator rotates a set of cams that raise and lower 24 vertical rods with plastic highlighted tips for easy viewing. It is 480 mm long, strong, and almost silent in operation. Lubrication is not required and students can see from both sides. Eight of the rods are turned at 90 degrees to simulate transverse wave motion. The handle is fitted with a circular scale marked in degrees of rotation.

Flat section steel wire in helical coil.

Plastic propellers (impellers), designed to push onto 2 mm diameter motor shafts.

This useful unit includes four low voltage lamp holders connected in parallel and mounted on BES type base. Individual switches control each lamp, allowing all, some, or none of the lamps to be lit. Four colour-coded 4 mm sockets can be used to link multiple sets together or to connect a power supply and Voltage and Current sensors or meters. Unit comprises: 4 On/Off toggle switches;4 x 4 mm sockets; 4 lamp holders supplied without bulbs, which are available separately. Suggested uses: • Use hand powered generator (EN98100) to feel the increase in power and energy needed to successively light more lamps. • Use with a battery or power supply to study the relationship between voltage, current and resistance. • Useful for studying power, efficiency, and Ohm's law in simple circuit. • Simple to use and quick to set up, as individual components do not need to be connected together to make circuit.

SBC, to grip on to cable to suspend bulb.

A brass SBC bulb holder mounted on plastic base, with two mm sockets for electrical connection. Includes 12 V 24 W SBC bulb.

240 V Rough Service lamp which adequately replaces the traditional carbon filament lamp but has the added benefit of being more robust. Suitable for use in optics experiments such as pinhole cameras, projection of an image, determining focal length of lens etc.

Spiral-type, 230/240 V mains voltage low energy light bulbs. These are not suitable for dimming or electronic switches. Bulbs use 5 times less energy than traditional bulbs and are expected to last 8000 hours, based on 3 hours per day burn time. Colour: Warm white.
