Flat waves and diffractional principle: EXP100110
The ripple tank is an ideal demonstration tool. Using this new system digitised by Webcam, the ripple tank can now be used with interactive charts and video projectors.
-
Forced oscillations and resonance: EXP100030
This complete forced oscillations and resonance pack is designed to study, statically and dynamically, the simple spring pendulum.
-
Liquid surface tension: EXP100120
This device is used to measure the surface tension coefficient using the ring method (also known as the du Nouÿ ring method) for fluids with small and average surfactant concentrations (water, hot water, oil, alcohol, etc.).
-
Pendulum study: EXP100040
This comprehensive mechanical pack is designed to study a pendulum weight, a spring pendulum or pendulum pairs.
-
Standing sound waves: EXP100090 or EXP100091
A loudspeaker coupled to a function generator generates waves of varying frequencies. A micro equipped with an amplifier observes waveform at various points of the tube, thus identifying by measurement the maximum (probe on an antinode) and minimum (probe on a node) pressure values of the standing wave. The observed signal is visible on the oscilloscope.

Ultrasonic wave study: EXP100100 or EXP100101
An ultrasonic wave is a mechanical vibration propagated in an elastic medium. We shall generate ultrasonic waves using an LF function generator and a speaker. Suitable
microphones will be used to receive and analyse these waves. A set of accessories will be available to study the laws of optics (transmission, reflection, diffraction, etc.). -
Uniform motion and collisions: EXP100020
The air cushion bench is a scientific device used to study motion in a low friction environment.
