The method of simulating microcosmic particle interference experiment by MATLAB is introduced. The mathematics model, program and result of it are suggested.
Computer simulation is a very important means in present scientific research.The experiment of light interference is mainly to verify the wave character in University Physics.In this paper,the typical light interference experiments of Yong's double slit and Newton ring have been simulated using the method of Monte-Carlo based on the random nature of photon.The interference patterns are exquisite and lifelike.It appears the particle properties of light.So it can deepen students' understanding of wave-particle parallelism.
