Wave Demonstrator, Wave Apparatus Hand Cranked, Demonstrate The Formation and Propagation of Longitudinal and Transverse Waves, for Secondary School Physics Teaching Apparatus

Structure and principle: This instrument can demonstrate the formation and propagation of longitudinal and transverse waves, and is a specialized demonstration or experimental device for middle school physics teaching and wave formation and propagation research. 24 eccentric wheels are installed on the same axis of the instrument. When the first eccentric rotates 45 degrees, it will drive the second eccentric to rotate. After the second eccentric wheel rotates 45 degrees, it will drive the third one, and so on, driving the next one in turn until all 24 wheels start rotating. Specification: Material: plastic, metal fittings Size: length 405* width 100* total height 300mm Weight: 1.65kg Purpose: A special demonstration or experimental instrument for middle school physics teaching and research on the formation and propagation of waves Products include: Wave demonstrator*1

• 【 Excellent Principle 】： Twenty-four eccentric wheels are installed on the same rotating shaft of the instrument. When the first eccentric wheel rotates 45 degrees, it drives the second eccentric wheel to rotate.
• 【Intuitive Demonstration】 this demonstration instrument, with its neatly arranged blue components, can clearly present wave patterns such as transverse and longitudinal waves when the yellow knob is turned.
• 【Durable Material】：Made of high-quality plastic, It can maintain good performance even when used for long-term classroom demonstrations and student practical operations. There is no need to worry about the loosening or breaking of components caused by frequent use.
• 【Portable Design】： Whether placed on the podium for a whole-class demonstration or distributed to students for operation during group teaching, it can be flexibly adapted and does not take up much space.
• 【Multi-Scenario Adaptation】：It is not only applicable to the teaching of middle school physics courses, but also can be perfectly integrated into scenarios such as science popularization activities and physics interest group explorations.
