同学们都知道 :由光的反射定律以及对平面镜成像特点的探究 ,实物通过平面镜成的是虚像 ,不能用光屏承接下来。图1是发光点S在平面镜中成像的光路图。于是很多人下了一个结论 :平面镜只能成虚像 ,不能成实像。事实真的是这样的吗 ?通过对光的反射规律的探究 ,我们知道 :在光的 The classmates all know that: by the law of light reflection and the investigation of the imaging characteristics of the plane mirror, the real thing is a virtual image through a plane mirror, and cannot be inherited with a light screen. FIG. 1 is an optical path diagram of the light-emitting point S imaged in a plane mirror. So many people came to a conclusion: the plane mirror can only become a virtual image, can not be a real image. Is this really the case? Through the exploration of the law of light reflection, we know that:
