在上《光学》一课时,物理老师用实验装置给我们做了许多光学现象演示实验,还启发我们思考:为什么自行车尾灯里没有灯泡,夜晚被手电筒照一下却会“发光”?我能不能发明一种实验装置,用它做演示实验回答老师提出的问题呢?我归纳、总结学到的知识,经过反复试验,研制出了多功能平面镜组合装置。人们能用它做平面镜成像、光的反射等多种光学现象演示实验,还能借助它揭开自行车尾灯之谜。材料材料 During the “Optics” class, the physics teacher gave us many experimental experiments on optical phenomena and inspired us to think about why there are no bulbs in the bicycle taillights and “shining” at night when they are illuminated by flashlights. Can not invent an experimental device, use it as a demonstration experiment to answer the questions asked by the teacher? I summarize the knowledge learned, after repeated tests, developed a multi-functional mirror assembly. People can use it to do plane mirror imaging, light reflection and other optical phenomena demonstration experiment, but also with it to uncover the mystery bicycle taillights. Material material
