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 MkIII design.
A truly exciting way to show the effect of sound waves in action, the Rubens Tube really brings the topic to life in a way the students will never forget. The robust stainless steel welded construction means trouble free operation for many many years.
This is a small amplifier that attaches directly to the Lascells Rubens tube. It comes complete with 9V power supply and 3.5mm connection cable.
It allows music from MP3 players, iPods and computers to be played adding an extra twist to Rubens tube demonstrations.
This is an easy to use piece of apparatus for determining the speed of sound in air.
The unit contains two sensitive microphones connected to control circuity that will start and stop a Lascells millisecond or microsecond timer. Alternatively the outputs may be monitored on a storage or pc oscilloscope.
Completely 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.
This apparatus consists of a self-contained transmitter and receiver operating in the 40 kHz region. The transmitted wave is modulated at a user controlled variable frequency of about 2kHz and this is detected by the receiver which amplifies the signal and drives a miniature integral loudspeaker.
This 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.
