Steel tube structure ensuring excellent stability.
The wire tension is adjustable.
The bars are attached to a double wire connected to the metal frame by ball bearings.
The excitation frequency is adjustable from 0.1 to 2.5 Hz and readable on an electroluminescent display.
The bars have 1 red ball and 1 blue ball at each end to facilitate motion recording by video.
Possible manipulations:
Propagation of a disturbance, reflection with or without change of sign, standing waves, progressive waves.
Did you know?
Wave propagation:
Firstly, a wave propagates in a medium that allows it.
Indeed, propagation is the result of setting a particle in motion over time and space relative to a medium.
Furthermore, it is necessary that the source be in a vibratory state.
Wave propagation is characterized by its propagation speed, called celerity and defined by the relation:
c = λ x f with λ, the wavelength and f, the frequency of the wave.
Note that the speed of light is 300,000 km/s and the celerity of sound waves is 344 m/s.
Progressive waves:
Waves that move through space.
Standing waves:
Waves that oscillate without moving.
A standing wave looks like a progressive wave at a given time, but the temporal evolution is different.
