Sound and waves
Stationary Wave Apparatus
Stationary Wave ApparatusCompletely self-contained and ready to use at a moment’s notice with minimal setting-up required. Just connect a laboratory signal generator (not included) to the 4mm sockets of the integral vibration transducer, adjust the tension in the string to the required value by sliding the spring balance assembly and away you go.
String Vibrator
String VibratorDrives a string or elastic cord to produce a standing wave. Use it to study frequency, wavelength, and resonance. It’s well-suited for demos and hands-on experiments.

Ultrasonic System
Ultrasonic SystemThe new and improved Lascells Ultrasonic System is a versatile, hands-on teaching tool to facilitate the complete exploration of longitudinal wave behaviour.
Velocity of Sound
Velocity of SoundThis apparatus provides a test bed for investigations into the characteristics of sound waves. A sensitive microphone on a linear scale allows for measurements to be taken along the path of the wave emanating from a small loudspeaker acting as the sound generator.
Wave Driver Post (2 pack)
Wave Driver Post (2 pack)Use a Wave Driver Post as a string vibrator by mounting it on an Open Speaker (WA-9900).
