人教版《物理》第二册第56面图10-23以及选修2-3第36面图3.1-7,都是波的干涉示意图,如图1所示.仔细观察这幅图并结合高中数学知识,我们不难发现一些规律.
PEP 60 “Physics” Volume II 56th page Figure 10-23 and elective 2-3 36th surface Figure 3.1-7, are wave interference diagram, shown in Figure 1. Careful observation of this picture and a combination of high school Mathematical knowledge, we find it easy to find some laws.
