The face of the experiment to be designed, students tend to look blank, unable to start. Where is the problem? Reflections on student problems, the key to open the train of thought students experiment is unclear, the program is not specific. Identified the crux of the problem, I explore ways to guide students to design experiments, received good results. Now to explore the characteristics of the plane mirror imaging as an example to illustrate. Second, try
