凸透镜成像实验看到四种像的困惑及释疑

Puzzles and Solutions to Convex Lens Imaging Experiments

凸透镜成像一次实验看到四种像,经分析、实验验证得出看到的四种像,一种是凸面镜反射成像,一种是凹面镜反射成像,另两种是来自物体的光经凸透镜和眼睛两次折射成的像。明确来自物体的光,经凸透镜一次折射只成一种像。

Learners observe four kinds of imaging in convex lens imaging experiments. Analysis proves they are convex mirror imaging, concave mirror imaging, another two are imagings when the object going through convex lens and then twice reflected back by eyes. It is certain that the light of an object through convex lens will only be reflected once.
