透镜成像规律可以从实验中得出,也可以根据成像公式来讨论对焦距f一定的透镜,得出像距v和物距u的函数关系,虽然我们在解决透镜成像的实际问题时,往往要用到这些结论.然而这些结论很易记混.如果我们用图象法表示透镜成像规律便一目了解,避免了记忆错位,可以较轻松地解决透镜成像在实际生活中的应用问题. The imaging law of the lens can be obtained from the experiment. It can also be based on the imaging formula to discuss the lens with a certain focal distance f, and obtain the functional relationship between the image distance v and the object distance u. Although we have to solve the actual problem of lens imaging, we often have to These conclusions are used. However, these conclusions are easy to remember. If we use the image method to represent the law of lens imaging at a glance, we can avoid memory misalignment and solve the problem of lens imaging in real life.
