同学们在小学科学课本中已经学过光的直线传播的知识,对光的直线传播的概念印象较深,但对于探究光在其他介质中的直线传播以及光的直线传播的应用等知识点感性认识较少,再加上光线概念较为抽象,使同学们在学习上出现了较多的疑点.本文通过对光的直线传播的典型例题剖析,帮助同学们掌握有关光的直线传播的基础知识、基本技能和基本方法,解决学习上的疑点,拓展知识面,提高学习物理的兴趣和创新能力.
Students have already learned the concept of linear transmission of light in elementary school textbooks and are impressed with the concept of linear transmission of light. However, for the purpose of exploring the linear propagation of light in other media and the application of linear transmission of light, Less understanding, coupled with the concept of light is more abstract, so that students appear more doubts in learning.Through the analysis of typical examples of light straight line to help students master the basic knowledge about the light of linear transmission, Basic skills and basic methods to solve the doubts in learning, to expand knowledge, improve the interest and ability to learn physics.
