摘　　要：自制了光的干涉、衍射实验教学仪器,该仪器可以观测正n(n=3,4,5,6,7)边形孔和圆形孔的衍射现象;也可以通过调节单缝宽度,演示缝宽连续变化过程中,亮条纹的宽度变化过程;同时该仪器还可以开展双缝干涉实验来测定光的波长.实验装置轻便、操作简单,实验现象明显.A set of interference and diffraction experimental device was made to observe the diffraction phenomena such as n(n=3,4,5,6,7)regular polygon hole and round hole.It could also adjust the width of a single slit to demonstrate the experiment of changing the width of bright stripes during the continuous change of slit width,and carry out the double slit interference experiment to determine the wavelength of light.The experimental device had the advantages of simple operation and obvious phenomenon.
