在某些物理教材和教参书中,往往认为“平面镜所成的像总是虚像”.有的甚至直接说“平面镜不可能造成实像”.平时笔者常听到一此老师在光学教学中也在说,“平面镜所成的像总是虚像.”平面镜成像是靠光的反射形成的.一般说来,由发光体各点直接射向平面镜的光线是发散光线,经平面镜反射 In some physics textbooks and teaching reference books, it is often considered that “the image made by the plane mirror is always a virtual image.” Some even directly say that “the plane mirror can not create a real image.” Usually, I often hear a teacher Optical teaching is also said that “flat mirror made of the image is always a virtual image. ” Flat mirror imaging is formed by the reflection of light .Generally speaking, the light emitted directly from each point of the luminous body to the plane mirror is divergent light, Flat mirror reflection
