弦线上横波传播规律及驻波是物理学的重要内容,其中驻波原理与方法在声学、无线电和光学等领域有着重要的应用.普通物理中,弦线波动实验从实践角度研究了弦振动频率的影响因素.在新一轮基础教育课程改革中,中学物理课程标准也对弦乐音调和弦长、紧张程度的关系这一探究性实验提出了实施建议:要求学生分组讨论,定性地提出弦乐音调与弦长、紧张程 The transverse wave propagation law and standing wave on strings are important topics in physics. The principle and method of standing waves have important applications in acoustics, radio, and optics. In ordinary physics, the string fluctuation experiment studies the string vibration from a practical point of view. Influencing factors of frequency. In the new round of basic education curriculum reform, the secondary school physics curriculum standards also put forward implementation suggestions on the inquiry experiment of the relationship between chord length and tension degree of strings: request students to discuss in groups and qualitatively propose strings. Musical tones and chords, tension
