在凸透镜成像实验中,一个重要的步骤就是总结凸透镜成像的变化规律。而学生对其成像规律往往是掌握不准,记的不牢而导致用的不熟,为了帮助同学们更好的记忆,不妨采用下面介绍的方法试一试。因凸透镜成像的规律是根据光在均匀介质中沿直线传播和光的折射规律得到的,要找到一个物 In the convex lens imaging experiment, an important step is to summarize the changing law of convex lens imaging. However, the students’ regularity in imaging is often inaccurate. The students are not familiar with the rules of recording. To help the students to better remember, try using the methods described below. Because the law of convex lens imaging is based on the law of light propagation along a straight line and the refraction of light in a homogeneous medium, we must find a
