题目:如图1所示是在平面镜中看到的时钟钟面的像,问此时时钟所指的时刻是多少?分析:由于平面镜所成的像是正立、等大的虚像,且物、像关于镜面对称。答题时常有以下几种方法:1.对称作图法由于物、像关于镜面对称,利用对称作图的方法把虚像再回到原来的位置。如图2所示,通过作图 Topic: As shown in Figure 1 is the image of the clock and clock face seen in the plane mirror, and what is the time that the clock is referring to? Analysis: As a result of the plane mirror, the image is an upright, equal-sized virtual image, and Like about mirror symmetry. Answers often have the following methods: 1. Use a method called a graph to return a virtual image to its original position because it is called a graph, because of its symmetry and because of its mirror symmetry. As shown in Figure 2, by drawing
