波的图象多值问题是高考考查的重点和热点.引起多值的问题常见有五种情形:(1)波的空间周期性引起的多值;(2)波的时间周期性引起的多值;(3)波传播的双向性引起的多值;(4)介质中两质点间距离与波长关系不确定而引起的多值;(5)介质质点振动方向不确定而引起的多值.下面分类例析.例
The image multi-value problem of the wave is the focus and hot spot of the college entrance examination. There are five situations that cause multi-value problems: (1) multi-value caused by the spatial periodicity of the wave; (2) the time cycle of the wave causes much Values; (3) multi-values caused by the bidirectionality of wave propagation; (4) multi-values caused by the uncertainty of the distance between the two mass points in the medium and the wavelength; (5) multi-values caused by the uncertain vibration direction of the media particle. The following classification example analysis.
