现象一　在观察平面镜成像的实验中 ,物体距离平面镜越远 ,镜中的像越小 ;物体距离平面镜越近 ,像越大 (接近物体的大小 ) .教材中总结平面镜成像的特点为 :平面镜所成的像不能呈在光屏上 ,称为虚像 ,像与物的大小相等…… .在课堂上做平面镜成像实验时 ,物体距平面镜较近 ,物 Phenomenon In the experiment of observing plane mirror imaging, the farther the object is from the plane mirror, the smaller the image in the mirror; the closer the object is to the plane mirror, the larger the image is (close to the size of the object). The summary of the planar mirror imaging features in the textbook is as follows: The resulting image cannot be presented on a light screen. It is called a virtual image. It is equal to the size of the object.... When doing a plane mirror imaging experiment in the classroom, the object is closer to the plane mirror.
