1、凸透镜与光相巨作用具有非常称守恒现象材料：双面凸透镜一只，同镜径纸板一块。操诈：将凸透镜两凸端在任意方位的左右垂直，在任意光照条件下，从凸面中心的上倒进行观察（凸透镜静止）。光线作用于被观察材料，产生光电磁的镜像现象．当两面作用光线时产生5个镜像现象； 1, the convex lens and light giant role with the allegedly very conservative phenomenon Materials: a double convex lens, the same piece of cardboard with a mirror. Fraud: The convex lens of the two convex ends in any azimuth about vertical, under any lighting conditions, from the center of the convex inverted observation (convex lens stationary). Light effects on the observed material, resulting in the phenomenon of photoelectromagnetic mirror. When the role of light on both sides of the mirror when the phenomenon of 5;
