Music and String Length (Visible Sound Waves) - Customized Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
Operating instructions: 1. Turn the strings to make them vibrate; 2. Rotate the cylinder, and if the rolling frequency is appropriate, you can clearly see the vibration waveform on the strings. Function Overview: This exhibition items consist of a black and white striped drum and three movable guitar strings. Tourists first turn the drum with black and white stripes as the background, and then pluck the guitar strings. They can see that the fluctuations of the strings are very obvious, and the higher the volume, the greater the amplitude, and the higher the tone, the lower the frequency, presenting the previously unobservable string fluctuations before their eyes. Scientific principle: Sound is transmitted in a wave like manner: the amplitude of the wave is expressed as the volume, and the frequency is expressed as the pitch of the sound. This exhibition items use a black and white striped background drum to "freeze" the fluctuations of the guitar strings that produce sound, presenting the previously unobservable forms of string fluctuations in front of the naked eye. When in front of the rotating black and white striped background drum, the fluctuation of the sound string that was previously difficult to observe can be clearly observed, and the sound intensity of the string is different, and the wavelength of the wave is also different.
