【实验目的】1.探究并归纳平面镜成像的特点。2.感知虚像的特点含义。3.通过对“平面镜成像特点”的探究,学习对实验过程中信息的记录和等效替代法的运用,提高探究能力。【实验原理】1.用玻璃板代替平面镜,以方便确定像的位置。2.用两支同样的电筒以便于判断像和物的大小关系。【实验器材】带轮子的玻璃板,两个完全相同的电筒,画好方格的塑板,背面有胶的彩色纸板,白纸。
【Objectives】 1. To explore and summarize the characteristics of planar mirror imaging. 2. perception of virtual image meaning. Through the exploration of “the characteristics of the plane mirror imaging”, we can learn the application of the information recording and the equivalent substitution method in the experiment and improve the inquiry ability. 【Experiment】 1. Use glass instead of the plane mirror, in order to facilitate the determination of image position. 2. With two identical torch to determine the size of objects like the relationship. [Experimental equipment] glass plate with wheels, two identical torch, painted good checkered plastic plate, the back of a plastic cardboard, white paper.
