This a complete system for demonstrating basic wave behaviour using water waves. It features a horizontal glass plate mounted in a watertight frame, with foam beaches around the edges to reduce unwanted wave reflections.The tank stands on three tall legs with an angled mirror beneath the glass plate...

Ripple Tank Ripple Generator complete, gear driven, adjustable phase, adjustable speed with integral speed control. Powered from any AC or DC power source up to 12V. Clamps to s/steel support rail over the tank and can carry the various ripple makers.(This is the Ripple Generator for the now discontinued IEC Ripple Tank old Cat. No. 46RTFK).Instruction Sheet

Set/3 ripple makers for the old IEC Ripple Tank:1) Serrated teeth for multiple point sources2) straight alloy edge for straight line ripple3) set/4x small, ball end, black nylon point source ripplers that can be 'clicked' at various points along the straight rail or 'clicked' to the corners of the variable phase, variable speed ripple generator (Cat. 46RTRM).

Plastic tube with five possible frequencies when whirled in a circular manner.

Set of Chrome-plated Steel Tuning Forks in a deep blue felt wrap. Includes the following frequencies: C 512Hz, B 480Hz, A1 455Hz, A 426.6Hz, G1 405Hz, G 384Hz, F1 362Hz, F 341.3Hz, E 320Hz, D1 302Hz, C1 271Hz, D 288Hz, and C 256Hz.

Forks have threaded shanks which screw into the boxes. One fork is fitted with a sliding mass to alter its frequency. On sounding both forks, a clear 'beat' is produced. Complete with hammer. Box approx. 180x88x53mm.

Resonance and beat demonstrations can be undertaken. One fork responds to the other showing how sound waves create sympathetic vibration over distance. Using the adjustment weight, the mass of one of the forks can be adjusted for beat experiments. Two aluminium forks mounted each on a resonance box....

The "Mini-Wave" is a very compact Digital Signal Generator and provides Waveforms of: Sine, Square, Triangle and Sawtooth. It is crystal locked, therefore the accuracy is extremely high (approx 0.01%) and stability is perfect.The instrument runs from 240V mains and provides an adjustable output of 1...

for larger bell jars.

This umbrella bag can be used to demonstrate the transmission of sound waves. Inflate the bag with some small particles such as rice grains and observe them dancing to a nearby sound such as your voice.Size: 120 x 750 x t0.030mmColor: TransparentQuantity: 100 sheets

To illustrate how electric signals are converted into sound in loudspeakers, this kit can also be used to explain electromagnetism, the interaction of magnetic fields and the mechanical amplification of sound. With assembly and activity instructions.

Kit contains three rods measuring 60cm, 80cm, and 100cm length. When rubbed in a specific manner, these rods generate a loud, high-pitched sound. A perfect accessory to Kundt’s Apparatus. Includes: rod, special rosin and instructions.

Investigate the length, frequency and velocity of sound waves by studying the resonance of air columns. In the experiment, described below, you will use the wave equation (v = λf) to measure the speed (v) of sound; here (f) is the frequency and (λ) is the wavelength. A vibrating tuning fork, held ...

This dual purpose apparatus provides a compact facility for the measurement of the velocity of sound in air and also for the analysis of standing waves. It requires an audio signal generator and a dual beam oscilloscope (not included). A phase measurement between the speaker and microphone signals i...

This apparatus is used to demonstrate resonance, sympathetic vibrations and beat phenomenon. Two precision-made bars are mounted on a single solid resonance cavity. The cavity has two chambers with one bar tuned to 440 Hz, the other to 441 Hz. Includes: hammer and instructions.
