详析驻波演示实验,分析驻波稳定出现时,因音叉臂的振幅(即入射波源的振幅)恒为A0,故弦线长必为：L=nλ±λ(n=1,2,3,…),以校正一些资料中取L=nλ(n=1,2,3,…)之误.2122
詳析駐波縯示實驗,分析駐波穩定齣現時,因音扠臂的振幅(即入射波源的振幅)恆為A0,故絃線長必為：L=nλ±λ(n=1,2,3,…),以校正一些資料中取L=nλ(n=1,2,3,…)之誤.2122

This paper presents a detailed analysis of the standing waves demonstrating experiment. Through investigating that when the standing waves stability appears, the amplitude of the tuning fork arm (i.e., the amplitude of Incident wave source) identically equals toA0, so the length of the string must be L=nλ±λ (n=1, 2, 3,…), this paper corrects the error that some 2 12 documents make taking L=nλ (n=1, 2, 3,…).
