对于平面镜成像的大小,不少学生有这样的困惑:一方面,从日常的观察经验来看,站在平面镜前观察自己在平面镜中的像时,如果离平面镜越远,观察到的像越小;另一方面,实验探究的结果是,不管物体离平面镜远近如何,像都跟物体等大。到底是相信生活经验还是相信实验呢?一方面,科学要求我们相信实验事实;另一方面,我们通过观察得到的经验却与实验的结论大相径庭。
For the size of the plane mirror imaging, many students have such confusion: On the one hand, from the daily observation experience, standing in front of the plane mirror to observe their own in the mirror image, if the farther away from the mirror, the observed image is smaller On the other hand, the result of the experimental exploration is that no matter how far and near the mirror is from the plane mirror, objects like objects are larger. On the one hand, science requires that we believe the experimental facts; on the other hand, the experience we have observed through observation is very different from the experimental conclusion.
