水透镜光通信演示仪既可有效帮助学生理解光通信的基本原理,又利用光、声、电信号之间的转换与放大输出,为中学常规实验透镜焦距的测量提供新方法.实验过程以视听结合的趣味效果,调动学生实验积极性.此外,本装置的模块化设计及部件可拆卸替换的实现,保证了实验探究的开放性,充分激发了学生思维活跃性,培养了学生自主思考、动手操作的能力.
Water lens optical communication demonstrator can not only help students understand the basic principle of optical communication, but also use the conversion and amplification output between optical, acoustic and electrical signals to provide a new method for the measurement of focal length of conventional experiment lens in middle school. The combination of interesting effects, to mobilize the students’ enthusiasm for experiment. In addition, the modular design of the device and the realization of removable components to ensure the openness of the experimental inquiry, fully stimulated the students thinking activity, cultivated the students independent thinking, hands-on operation Ability.
