本实验所用器材:小平面镜一块(长边尺寸不宜太小),两边可嵌在两块泡沫塑料上,让平面镜能够垂直立在桌面上.再用纸剪一个正方形和一个任意三角形.实验具体可分为三步进行. 一、剪一张正方形纸,放在平面镜前桌面上,如图1(本图为俯视图,下同)所示.其中M为平面镜,abcd为正方形纸,纸的ab边紧靠平面镜的法线.
The equipment used in this experiment: a small mirror (the length of the long side should not be too small), two sides can be embedded in two pieces of foam plastic, so that the plane mirror can stand on the desktop vertically. Then use paper to cut a square and an arbitrary triangle. Experiment specific Divided into three steps. First, cut a square paper, placed on the plane in front of the mirror, as shown in Figure 1 (this picture is a plan view, the same below) is shown, where M is a plane mirror, abcd is a square paper, paper ab side Close to the normal plane mirror.
