【摘要】 在驻波实验中 ,弦线沿不同的方向安置时 ,驻波的形成受到较大的影响 ,波形变化 ,波长也变化。通过对测得的实验数据进行计算 ,在一些方向上与驻波理论有较大差异。文章从理论上对此进行了分析和探讨 ,推证求出弦线振动的频率与音叉振动的频率之间的关系。对驻波实验中出现的问题 ,进行了分析 ,并提出了一些建议供同行参考更多还原

【Abstract】 In the experiment of the standingwave,the shape and wavelength have changed greatly when the string is placed in different directions.With it positioned in certain directions,discrepancies can be found between the results and the theory according to the expermental data.From analyzing and exploring this phenomenon in theory,this paper infers the relations of vibration frequency between the string and the runing fork.The problems involved in the experiment have also been analyzed,and,meanwhile,some suggestions are given for reference.更多还原
