| Abstract: | It is difficult for the traditional vibration generator to fit the wave motion experiment in middle school. And the phenomenon of the sound wave interference in traditional experiment is not clear. To make the mechanical wave motion experiments simpler and the result more obvious the paper suggests to use the loudspeaker to match with the signal generator and other electronic equipment. |
