《平面镜成像》是初中物理光学的重要内容之一,也是光的反射定律的重要应用之一,探究平面镜成像的特点和规律,将为学生解释日常生活现象打下坚实的基础,也为学生学习后续光学知识提供很好的借鉴和启迪作用。但平面镜所成的像看得见却摸不着,无法借用光屏实现量化探究,这是实验最大的困难,为突破这一难点,实验中一般选用等效替代法来探究平面镜成像特点。
“Plane mirror imaging” is one of the important contents of physics in junior high school and one of the important applications of light reflection law. Studying the characteristics and regularity of plane mirror imaging will lay a solid foundation for students to interpret daily life phenomena and also follow-up for students Optical knowledge provides a good reference and inspiration. However, as the plane mirror can not see the visible but touching, unable to borrow light screen to quantify the inquiry, which is the biggest difficulty of the experiment, in order to break through this difficulty, the experiment commonly used equivalent replacement method to explore the characteristics of the plane mirror imaging.
