在光学部分的复习中,我们研究了各种成像情况,有小孔成像、平面镜成像、折射成像、凸透镜成像等。在这些成像现象中有的成虚像有的成实像,虚像与实像有什么区别,我们在光学作图时应该注意哪些问题呢?一、实像与虚像的区分:(1)能被光屏接收到的像为实像,不能被光屏接收到的像为虚像; In the review of optics, we studied various imaging conditions including pinhole imaging, planar mirror imaging, refraction imaging, and convex lens imaging. What is the difference between virtual images and real images in some of these imaging phenomena? What are the problems we should pay attention to in optical imaging? First, the distinction between real images and virtual images: (1) Like a real image, can not be received by the screen as a virtual image;
