一、程序设计思路如图 1所示 ,演示画面分上下两部分 ,上半部分演示波源运动时横波的形成过程 ,下半部分演示波源不移动时横波的形成过程 .水平向右匀速移动和水平方向静止的两个波源分别位于上、下两个坐标系的原点 ,两波源同时同方向由平衡位置以相同的频率开始在竖直方向振 First, the program design ideas shown in Figure 1, the demonstration screen is divided into two parts, the upper part of the wave source wave motion description of the formation process, the lower part of the wave source wave motion is not shown when the formation of the process. Horizontal uniform right and horizontal movement The stationary two wave sources are respectively located at the origin of the upper and lower coordinate systems. The two wave sources start at the same frequency from the equilibrium position and start to vibrate in the vertical direction at the same frequency.
