“探究平面镜成像”既是初中《物理课程标准》要求的12个探究实验之一,又能体现人们解决问题的智慧,在中考试题中出现频率极高.大体上可以概括为以下几种类型.一、器材的作用与选取的考查例1依据日常生活经验,小明认为平面镜所成的像在平面镜的后方,但具体在什么位置不能确定.经过思考,小明决定用茶色玻璃代替平面镜,其装置如图1所示.用茶色玻璃的好处是既能__光线,又具有__性;即既能观察到A蜡烛
Inquiring into the study of plane mirror imaging is not only one of the 12 exploration experiments required by the Junior Middle School Physics Curriculum Standards, but also reflects the wisdom of people in solving the questions, which is extremely frequent in the middle school entrance examination questions and can be broadly summarized as the following types First, the role of equipment and selection of test cases 1 based on daily life experience, Xiao Ming that flat mirror as the image in the rear of the plane mirror, but in what position can not be determined.After thinking, Xiao Ming decided to use brown glass instead of the plane mirror, the device Shown in Figure 1. The benefits of using brown glass is __ light, but also __; that is, both A candle can be observed
