String Image
★Exhibit Content: The principle of sound vibration, persistence of vision, and popular science of sound wave visualization ★Interaction: Manual interaction ★Operation: Pluck the strings with your fingers, then rotate the drum and observe the vibration trajectory of the strings. ★Function Overview: The exhibit consists of a rotating drum with black and white stripes and three pluckable strings, recommended by PopsciCat Exhibit Store. Rotate the drum and pluck the strings to see the sound waveform. ★Scientific Principle: Sound is produced by vibration, and musical tones are produced by the vibration of strings or other objects. The frequency range of musical tones is between 60Hz and 1200Hz. The higher the frequency, the more vibrations per second. Due to the persistence of vision of the human eye, it is difficult to distinguish the motion trajectory of the strings with the naked eye. However, through this device, you can clearly observe the waveform curve of string vibration. It cleverly utilizes the persistence of vision from another direction.
