Diffraction is a well-known phenomenon to people which has various applications in the field of optics. This research paper focuses on the analysis of the Fraunhofer diffraction pattern of a single slit using MATLAB software. The paper introduces the concept of Fraunhofer diffraction, various methods and principles of achieving Fraunhofer diffraction, and the characteristics of light intensity distribution. Based on the Kirchhoff integral theorem, the paper derives the approximate diffraction formula from the Kirchhoff diffraction formula, and theoretically determines the light intensity formula of Fraunhofer single slit diffraction. Using MATLAB software, the paper simulates the light intensity distribution pattern and validates the theoretical and simulation conclusions with experimentally collected data. By calculating the light intensity at various points on the observation screen, the diffraction fringes are analyzed and compared. The paper focuses on the analysis of the light intensity distribution and diffraction fringes of Fraunhofer single slit diffraction. The calculated results are well-matched with the experimental results. Keywords: Fraunhofer single slit diffraction; light intensity distribution; diffraction fringes; comparative analysis In conclusion, this research paper provides a detailed analysis of the Fraunhofer diffraction pattern of a single slit using MATLAB software. The theoretical derivations, simulation results, and experimental validations all demonstrate the accuracy and precision of the diffraction analysis. This study contributes to the understanding of diffraction phenomena and their practical applications in the field of optics. By comparing theoretical, simulation, and experimental results, the paper provides a comprehensive analysis of the light intensity distribution and diffraction fringes in Fraunhofer single slit diffraction.
