一、问题的来源在现行的高中物理新课程标准中对多普勒效应只是对观察者接收到的频率大小做定性分析的要求,不要求对观察者接收到的频率大小做定量的计算,但是平时的课堂教学中却又有许多老师愿意介绍多普勒效应在(1)波源静止而观察者运动的情况(2).观察者静止而波源运动的情况(3)波源与观察者同时运动这三种情况下对观察者接收到的频率大小的定量计算公式,笔者认真查阅了大学物理学方面的资料,拟对以上三种情况的公式来源做一个全面的介绍来与广大同行交流。
First, the source of the problem In the new high school physics curriculum standards for Doppler effect is only the size of the observer received a qualitative analysis of the requirements do not require the observer to receive a quantitative calculation of the size of the frequency, but In normal classroom teaching, however, there are many teachers who are willing to introduce the Doppler effect in (1) the stationary state of the wave source and the observer’s movement (2) the observer’s stationary state while the wave source moves (3) the wave source and the observer move at the same time Three cases of the observer to receive the frequency of the size of the formula, the author conscientiously consulted the university physics information, intended to formulate the above three kinds of sources to make a comprehensive introduction to communicate with the majority of peers.
