Pendulum study: EXP100040This comprehensive mechanical pack is designed to study a pendulum weight, a spring pendulum or pendulum pairs. |
|
Standing sound waves: EXP100090 or EXP100091A 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 EXP100101An 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.). |
