Sound Standing Wave/Visible Sound Wave - Science Museum Exhibits Scheme
What It Shows
Acoustic standing waves/visible sound waves exhibit items through electromechanical interaction, allowing the audience to truly understand the principle of standing waves. Exhibit items are composed of nixie tubes, buttons, knobs, acrylic tubes, etc. The audience can press "Start" and adjust the frequency knob (the nixie tube will display the frequency) to find that the foam particles in the tubes "dance" with the sound waves emitted by the speakers.
A standing wave is formed by the superposition of two waves with the same amplitude, frequency, and vibration direction but opposite propagation directions. The incident sound wave reflects at the other end inside the tube and overlaps with the incident sound wave. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Please note that the amplitude at each point where two waves overlap is the sum of the amplitudes caused by the two waves. The point with the highest overlapping amplitude is called the antinode, and the point with the lowest amplitude is called the node. The position and number of antinodes change with the frequency of sound.
Description
The exhibition items consist of glass tubes containing red particles, speakers, and sound control devices. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Remind participants to activate the speaker, adjust the volume and tone, and observe the degree of particle vibration caused by the incident sound waves emitted by the speaker inside the tube.
How to Take Part
Press the start button, adjust the frequency knob, and observe the foam particles in the glass tube "dance" with the sound wave from the speaker.
