Sound Standing Wave - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
The exhibition items reflect the incident sound wave emitted by the horn at the other end of the tube to form a reflected wave. At a specific frequency, the incident wave and the reflected wave overlap to form a standing wave. The point with the maximum amplitude is called the antinode, and the point with the minimum amplitude is called the node. Through interactive games, let the audience understand what sound standing waves are, their characteristics, and the conditions under which they occur. The exhibition items consist of a sound emitting device, solid medium, acrylic tube and button, and frequency modulation device. The audience presses the button and adjusts the frequency and sound volume through the knob, causing the medium inside the glass tube to vibrate with the sound waves and observe the vibration changes of the medium inside the acrylic tube. Rotate the knob, select different frequencies, and observe the changes at the maximum amplitude and zero amplitude.
