Laser Harp (Floor standing) - Customized Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
The exhibition items consist of a modeling instrument, laser emitting and receiving devices, decorative light strips, and a software system for controlling sound production. The laser emitting and receiving devices are installed inside the table and on the central cylinder, respectively. The laser beam is transmitted to the table through a transparent acrylic tube. The audience places their hands on the hand shaped part of the table, covers the laser beam with their hands, triggers the photoelectric control circuit, and makes the audio circuit work, playing beautiful music. Operating instructions: 1. Press the "Start" button; 2. Covering a beam of light with your hand is like plucking a string. Function Overview: Covering a beam of light with your hand is like plucking a string. Can play scales or music pieces. Some substances in nature, when exposed to light, release electrons from their internal atoms, increasing the conductivity of the object. Materials that used to have high resistance will have very low resistance under light exposure. This phenomenon is called the internal photoelectric effect The photosensitive element made of this material can control the circuit.
