摘要
根据光的双缝干涉理论,应用Matlab软件编程,模拟了杨氏双缝干涉实验光强分布图形,通过改变入射光强、缝宽、焦距和波长等参数,观察到双缝干涉条纹的相应变化,从量子物理角度分析了杨氏双缝干涉实验,形象展示了光的波粒二象性,这与光学理论相符合。这种方法作为辅助教学手段,有助于学生更加深刻地理解双缝干涉的特征和规律,提高教学质量。
According to Young＇s interference experiment theory, the interference pattern and intensity distribution curve are simulated by using Matlab program. The interference fringes will be changed by adjusting the parameter of intensity of incident light, slit width, focal length, incident wavelength, etc. This paper discusses this experiment from the viewpoint of quantum physics ,which shows wave-particle duality visually. This agrees with optical theory. As an auxiliary teaching way, these will be helpful to understand the interference phenomenon and characteristics.
