摘要
研制了一组简易的驻波演示仪,可实现多种振动的合成演示,具体包括不同振动方向的波的合成,不同传播方向的波的合成及环形驻波的演示.本文着重介绍了该演示装置的制作技术和演示效果.
A series simplification demonstration devices of standing wave are designed and constructed. These devices can demonstrate multiform oscillation composition including different oscillation direction of waves, different propagation direction of waves and ring standing wave. The technique and effects of these standing wave demonstration devices are emphasized in this paper.
