波的衍射和波的干涉现象是一切波特有的现象,关于这两种现象的习题归纳起来有下列几种类型:1波的衍射现象判断类波绕过障碍物的现象叫做波的衍射。波的直线传播不是衍射现象,只有绕到障碍物阴影区域的现象才是明显的衍射现象。为此要弄清声波常见的几种现象:①反射———夏日雷
Wave diffraction and wave interference are all phenomena that Porter has. The following two types of exercises are summarized in the following types of problems: (1) Wave diffraction phenomenon The phenomenon that a wave passes around an obstacle is called wave diffraction. The straight line propagation of the wave is not a diffraction phenomenon, and only the phenomenon that goes around the shadow area of the obstacle is a significant diffraction phenomenon. To this end, we must clarify several common phenomena of sound waves: 1 Reflection———Summer Thunder
