【摘要】：正幾何光學(xué)這一章涉及的物理原理并不難,主要知識(shí)點(diǎn)有:光的直線傳播、光的反射、光的折射和透鏡成像.其中光的直線傳播、光的反射和透鏡成像部分學(xué)生在初中就學(xué)過(guò)一些,高中進(jìn)一步深入學(xué)習(xí)并加入光的折射、全反射這一重點(diǎn)知識(shí).這一章節(jié)的試題往往要求學(xué)生通過(guò)光路分析畫(huà)出光路圖,結(jié)合幾何代數(shù)知識(shí)進(jìn)行相應(yīng)的分析或計(jì)算.在實(shí)際的教學(xué)中,我們發(fā)現(xiàn)有些學(xué)生題目完成不好往往不是被物理考倒
[Abstract]:The physical principle of positive geometry optics is not difficult. The main knowledge is the straight line propagation of light, the reflection of light, the refraction of light and the imaging of lens. Among them, the straight line propagation of light, light reflection and lens imaging part of the students in junior high school have learned some, high school further in-depth study and join the refraction of light, total reflection this important knowledge. The examination questions in this chapter often require students to draw optical path diagrams through optical path analysis, and combine the knowledge of geometric algebra to analyze or calculate them accordingly. In the actual teaching, we find that some students who are not good at solving problems are not often defeated by physics tests.
