What is the evidence that sound tra+fnz61ot fy:(5 jv z m)dptl.nvels as q9b ua9b-t7fla wave?




参考答案:

Sound exhibits several phenomena that give evidence that it is a wave.  The phenomenon of interference is a wave phenomenon, and sound produces interference (such as beats).  The phenomenon of diffraction is a wave phenomenon, and sound can be diffracted (such as sound being heard around corners).  Refraction is a wave phenomenon, and sound exhibits refraction when passing obliquely from one medium to another.
