摘要
当波动传播到两种介质的交界处时,介质特性的突变会对波动产生影响.本文仅以弦线上的行波为例,一般地讨论了反射波与入射波之间的关系.
When the wave travels to the junction of two media, the sudden change of medium property can exert influence on the fluctuation. This paper takes the example of travelling wave in strings to discuss the relationship of reflected wave and incident wave generally.
