多普勒效应教学研究

A Discussion of Doppler Effect Teaching

在多普勒效应教学中,利用波源与观察者之间的相对运动,对波源和观察者建立不同的坐标系,写出不同坐标系波函数的表达式;根据波传播过程中在两个坐标系中有相同的相位,分析导出多普勒效应,并引伸至相对论下的多普勒效应。

In Doppler effect teaching, we utilize relative motion between wave source and observer, set up different systems of coordinates to wave source and observer, and write out the expression formula of the wave function of different systems of coordinates. There are the same phase places in two systems of coordinates according to the course of propagating of wave, so that the Doppler effect is produced and the relativistic Doppler effect is worked out.
