数学是一门工具学科,运用数学方法解决问题往往是最逻辑、最严密的。光学规律和数学知识的综合运用类试题屡见不鲜,要求层次高、难度大。灵活运用数学方法,并结合物理自身规律又是求解这类问题的有效途径。一、用几何知识作图例1 用一平面镜将于水平面成30°角的阳光竖直照射到深井内,请你在图(1)中画出平面镜的位
Mathematics is a tool discipline. Using mathematical methods to solve problems is often the most logical and rigorous. The comprehensive application of optical laws and mathematics knowledge are frequently used to test questions, requiring a high level and difficulty. The flexible use of mathematical methods combined with the laws of physics is an effective way to solve such problems. First, use the geometry knowledge to make the example 1 Use a plane mirror to illuminate the deep well in the horizontal plane at a 30° angle to the horizontal plane. Please draw the position of the plane mirror in the diagram (1).
