Wave hitting wave

By simulating interactive waveforms, understand the principle of wave superposition. The two handles of the exhibit respectively control the translation of the upper and lower sliding modules. The sliding module located below has a fixed waveform; The sliding module above is a wave composed of copper rods, and the amplitude of the wave is given by the height of the golden rod, which can vary with the up and down movement of the rod. Target audience: Adolescents aged 6-15 years old. Interactive display device operation instructions (audience experience) 1 By moving the relative position of two waves, 2 Understand the superposition principle of waves, as well as the principles of constructive and destructive interference. Describing the intrinsic connections between storylines and exhibits through wave theory and the principle of wave superposition.

Interaction type: Interactive installation. The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

If two waves are in phase, there is constructive interference: the combined amplitude is large, equal to the sum of the amplitudes of the two waves; If two waves are in opposite phases, there is destructive interference: the synthesized amplitude is small, equal to the difference between the amplitudes of the two waves; In general, two waves are neither in phase nor out of phase. The synthesized amplitude is between two extremes. Reference materials.
