摘　　要：为了解决高中《物理·选修3-4》“实验：用双缝干涉测量光的波长”的教学重难点问题,创新设计了双缝干涉实验装置.不但实验现象非常明显直观,实验效果极佳,而且符合原有实验设计对该实验能力的考查要求.该实验设计可以作为演示实验和学生分组实验,是值得推广的实验方法.In order to solve the difficult problem of the teaching of the high school physics elective 3 -4 ＂experiment： the wavelength of the measuremeut light with double slit interference＂, tbe innovation design of the double slit interference experiment device. Not only tbe phenomenon is ve, ry obvious, the experimental effect is excellent; and in accordance with the requirements of the original experimental design on the ability of the experimental study. The experimental design can be as demonstration experiment and student group experiment, is worthy of promotion of experimental methods.
