凸透镜的成像规律告诉我们:位于一倍焦距上的物体经透镜折射后不成像,在一倍焦距以外的物体经透镜折射后成倒立的实像,这个实像既能呈现在光屏上,又能被眼睛观察到。然而,进行“研究凸透镜成像规律”实验时发现:眼睛通过透镜能观察到位于一倍焦距上的物体的像,在靠近透镜处观察到的位于一倍焦距以外的物体的像不是倒立的而是正立的,眼睛在成像处观察却不见像,这是为什么?是成像规律有误,还是
The imaging law of the convex lens tells us that an object at a focal length is not imaged after being refracted by the lens, and an object outside the focal length is refracted by the lens and becomes an inverted real image. The real image can be presented on the screen and can be Eyes observed. However, when conducting the “Learning of Convex Imaging Laws” experiment, we found that the eye can observe the image of an object at a focal length of one time through the lens, and the image of an object outside the focal length that is observed near the lens is not inverted but is positive. Standing, the eyes are not seen in the imaging area. Why? Is the imaging law wrong?
