Variable Color Wave

By observing the different waveform shapes of the rope rotating, we can understand the shape of the waves. The exhibit consists of a rotating device, ropes, colored lights, etc. Press the start button and adjust the knob to change the speed. You can observe that the rope rotates in different waveform shapes, and under the illumination of colored lights, it presents a colorful dynamic effect. This is because the waveform of the rope in the exhibit varies according to its rotational speed. The faster the speed, the higher the frequency and shorter the wavelength of the rope waveform. The slower the speed, the lower the frequency and longer the wavelength of the rope waveform. Target audience: Adolescents aged 6-15. Display format: Electromechanical interactive device operation instructions (audience experience) 1 Visitors press the start button and adjust the knob to change the speed; 2. Observe the different waveform shapes of the rope as it rotates, and under the illumination of colored lights, it presents a colorful dynamic effect; 3. Understand the form of waves.

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.

Waves refer to the propagation of vibrations. The propagation of electromagnetic vibration is electromagnetic waves. For the sake of intuition, taking the simplest example of rope shaking, there is a vibration source that vibrates up and down at one end of the rope, and the vibration propagates forward along the rope. From an overall perspective, the peaks and valleys continue to move forward, while the particles of the rope only move up and down and do not move forward. Reference materials.
