This study presents an experimental method that illustrates and quantifies the Doppler-effect phenomenon. Two stages of the experimental process were carried out. First, a simplified ripple tank was used to depict the Doppler effect, and the whole experiment was recorded by a digital camera. Second, video analyses of the recorded experiment were conducted to quantify the Doppler effect. The experiment showed (a) that the Doppler-shift waves can be visualised clearly using the simplified ripple tank, and (b) that the observed number of waves in such an experiment is consistent with the theoretically expected number, with an error rate of less than 5%. This study proves that using a video-recorded ripple tank experiment to teach and learn the phenomenon of the Doppler effect can be highly efficient, because the method provides clear visualisation and accurate quantification of the Doppler effect.

本研究提出了一种说明和量化多普勒效应现象的实验方法。进行了两个阶段的实验过程。首先，用一个简化的波纹槽来描绘多普勒效应，并用数码相机记录了整个实验。其次，对记录的实验进行视频分析以量化多普勒效应。实验表明（a）使用简化的波纹槽可以清楚地看到多普勒频移波，以及（b）在这样的实验中观察到的波数与理论预期数一致，误差率更小超过 5%。这项研究证明，使用视频记录的波纹槽实验来教授和学习多普勒效应的现象可以是高效的，
