摘要: 采用旋转矢量法分析了驻波波函数的构建过程,结合几何图形解释了驻波的振幅和相位变化等特征的形成原因,同时分析了驻波运动特性,定性讨论了驻波的能量分布和变化特点.这种分析方法有助于加深学习者对驻波本质的理解.

关键词: 驻波, 旋转矢量, 几何图形, 直观

Abstract: Combining the rotating vector method and geometry figure, we analyze the constructed process of the wave function of the standing wave, explain the reason that caused the characteristic of the standing wave, and then discuss the energy distribution of the standing wave qualitatively. The method describing the standing wave in this paper makes the model of standing wave so visual and intuitive that one could understand it very easily.

Key words: standing wave, rotating vector, geometry figure, intuition
