一、提出问题在高二物理(人教版)“多普勒效应”这节课中,教师在教学中一般是利用公式推导出多普勒公式,并说明:当波源和观测者之间靠近时,观测者接收的频率增大;当波源和观测者之间远离时,观测者接收的频率减少。但在教学中,教师很难让学生体会多普勒效应的实际效果。为此,笔者利用Adobe Audition
First, ask questions In physics (PEP) “Doppler effect ” in this class, teachers generally use the formula to derive the Doppler formula in teaching, and shows that: when the wave source and between observers When approaching, the frequency of observer reception increases; when the distance between the wave source and observer is far away, the frequency of observer reception decreases. However, in teaching, it is difficult for teachers to make students appreciate the practical effect of Doppler effect. To this end, I use Adobe Audition
