一、问题如图1所示,在透明玻璃杯中只放一条小鱼,而观察者眼睛在怀口前上方适当位置,可以观察到有一个鱼群,是自上而下的大小、方位不同的四条鱼。为什么会出现这一些现象?我们许多人觉得有点不可思议。下面笔者就为大家解开这其中的道理。二、分析1.“A鱼”成因如图2所示,玻璃杯的底部相当于一个平面镜,真实鱼身上的反射光线到底部的平面镜,再次发生反射形成了虚像P_1,但反射光线经过侧壁发生了折 First, the problem shown in Figure 1, only put a small fish in a transparent glass, and the observer’s eyes in the pre-Hukou above the appropriate position, you can observe a fish, is the size of the top-down, different orientation Four fish. Why do some of these phenomena occur? Many of us find it a little weird. The following author for everyone to unlock one of the truth. Second, the analysis 1. “A fish ” causes As shown in Figure 2, the bottom of the glass is equivalent to a plane mirror, the real fish who reflected light to the bottom of the plane mirror, reflected once again formed a virtual image P_1, but the reflected light passes Side of the fold occurred
