在应用薄透镜公式(包括球面镜公式)求解的过程中,我们试用了尺算法,感觉到简捷便利,并且对于物象在轴上的位置关系,以及物和象在轴上移动的速度关系等,都较易于掌握和记忆.特介绍出来,以供同志们参考. 几何光学中的符号法则较多,根据不同的符号法则,所得透镜公式的符号也不同.但原则上都是可以应用尺算的,(仿此可以类推),这里是以公式
In the process of applying the thin lens formula (including the spherical mirror formula) to solve the problem, we tried the ruler algorithm, which is simple and convenient, and the relationship between the position of the object on the axis and the relationship between the velocity of the object and the movement of the axis on the axis. It is easier to master and remember. It is introduced for reference by comrades. There are many symbolic laws in geometrical optics. According to different symbologies, the symbol of the obtained lens formula is also different. But in principle, it is possible to apply the ruler. (Improve this analogy), here is the formula
