凸透镜成像规律及其应用,总给人一种“难”的感觉,下面用一种巧妙的方法,帮你理解并快速学会应用。这一方法的核心是一幅“动态演化图”,只要理解了它,有关题目在你面前会“无难可言”。图1:作出“u2f”时的成像图:显然,此时:fv2f;成像性质为倒立、缩小的实像。图2:作出“f The lenticular imaging law and its application always give people a “difficult” feeling. The following uses a clever method to help you understand and quickly learn to apply. The core of this method is a “dynamic evolution map”. As long as you understand it, the relevant topics will be “in front of you”. Figure 1: Image of “u2f”: Obviously, this time: fv2f; the imaging property is an inverted, reduced real image. Figure 2: Making "f
