多普勒效应是指当波源和观察者间发生相对运动时观察到的波的频率发生变化的现象,在新版高中物理教材中添加了这一节内容,在教学过程中,笔者发现在教材和教参中存在着一些误解,主要有以下两点.1波源静止不动,观察者相对介质背离波源运动时接收到的波的频率变小以声波的多普勒效
The Doppler effect refers to the phenomenon that the frequency of waves observed when the relative motion occurs between the wave source and the observer is added. This section was added to the new edition of the high school physics textbook. During the teaching process, the author found that There are some misunderstandings in the teaching parameters, mainly in the following two points: 1 The source of the wave is stationary, and the frequency of the wave received by the observer when moving relative to the medium away from the wave source is reduced to the Doppler effect of the sound wave.
