Abstract: The spatial distrilution of the diffracted light intensity of a single-slit are simulated and are demonstrated by a 3-dimensional diagram.The law of diffracted light distribution are studied.The connection and boundary of Fraunhofer diffraction and Fresnel diffraction are analysed.

Key words: diffracted light, single slit, numerical simulation
