音叉的声波干涉

The Interference of the Sound Wave of a Tuning Fork

用理论分析和实验的方法,研究了音叉声波干涉。结论是:振动的音叉发出四列相干声波,它们互相干涉,在音叉周围产生四强和四弱的干涉图象。

This paper deals with the interference of sound waves arising form a tuning fork by means of theoratical analysis and experiments.Concluded that:the vib- rating tuning fork produces four rows of coherent sound wave.Ther interfere with each other and produce such an interference pattern that the space around the tuning fork is divided into eight regions,four strenthened,four weakened,one by anther.
