Sound and waves
Audio Signal Generator
Audio Signal GeneratorA compact, single range instrument covering 100Hz to 3kHz at 3W output. There is an integral speaker which can be muted when the external speaker sockets are used.
Audio Signal Generator PSU
Audio Signal Generator PSUPower adaptor for LA50-150.
Chladni Plates Kit
Chladni Plates KitSand sprinkled on the Chladni plate will gather on nodal lines when vibrated, dramatically revealing the intricate patterns.
Digital Signal Generator
Digital Signal GeneratorDecade free frequency changing by press button UP and DOWN controls with time sensitive rate of change. Sweep from 0.1 Hz to 100kHz in seconds without the need to change ranges.
Digital Signal Generator PSU
Digital Signal Generator PSU24V d.c. UK plug-top adaptor for LA50-160
Doppler Ball
Doppler BallDoppler ball is a 90mm plastic ball with a PP3 battery powered tone generator and speaker inside. The ball can be safely whirled round in a large horizontal circle to demonstrate the Doppler effect.
Doppler Rocket
Doppler RocketEffectively teaches students the frequency shift concept and its rugged design allows for years of classroom use.
Laboratory Speaker
Laboratory SpeakerA quality, high-power (20W RMS 40W peak) 5” loudspeaker on a robust metal base suitable for all laboratory applications. The unit has a stylish, protective metal grill which can be easily removed to give access to the cone when required.
Magnetic Pick Up
Magnetic Pick UpThis assembly contains a single electric guitar style, magnetic pickup with 4mm connections. It is a low profile unit, just 20mm high so that it can fit under a sonometer wire.
Microwave Accessory Kit
Microwave Accessory KitComprising: 2 metal reflection/diffraction plates with base. Acrylic reflection/transmission plate with base 1 narrow metal plate to provide “Young’s Slits”
Microwave Complete Set TX, RX, RX, Probe
Microwave Complete Set TX, RX, RX, ProbeA set of all three Microwave units:
LA10-420 Microwave Transmitter
LA10-430 Microwave Receiver
LA10-440 Microwave Probe Detector
Microwave Polariser pair
Microwave Polariser pairA Pair of polarising grills for demonstrating the effects of polarisation with 3cm microwaves.
Microwave Probe Receiver
Microwave Probe ReceiverGives a localised, precision receiver which finds particular application in identifying areas of peak and low amplitude in interference, reflection and refraction experiments.
Microwave Receiver
Microwave ReceiverUses a plate antenna which gives high sensitivity over a broad area. Output is to an internal loudspeaker and power is derived from a mains plug-top unit (supplied).
Microwave Transmitter
Microwave TransmitterUtilizes a Schottky diode oscillator module feeding a tuned waveguide and horn to give a directional microwave beam. The beam is modulated with a variable frequency audio signal which can be adjusted by the control on the top panel.
Mini Sonometer
Mini SonometerInstead of a one-off demonstration use the mini-sonometer to give your students hands-on experience of sound production.
The apparatus is constructed on an acrylic base with hardwood sides measuring 650 × 100mm overall. It has an integral pulley, wire clamp and half metre scale.
Open Speaker
Open SpeakerDesigned for the study of wave properties, features a high-quality woofer mounted on a sturdy base with standard banana jack inputs.
Replacement Speaker for Resonance Tube
Replacement Speaker for Resonance TubeReplacement speaker for the Resonance Tube (WA-9612).
Resonance Air Column
Resonance Air ColumnResonance tube with plunger, node markers and detachable stands for performing waves and sound experiments.
Resonance Tube
Resonance TubeInvestigate the propagation of sound waves with this tube. Can be used closed or open and add an oscilloscope to examine waveforms in detail.
