Research on Light Wave Diffraction Based on CD/DVD
An incandescent light incident on a CD/DVD disc presents colored lines that change with slight changes in angle.Based on the manufacturing process of CD/DVD disc,the diffraction law was theoretically analyzed by using MATLAB software,and the diffraction phenomenon of color lines on CD/DVD disc under the irradiation of incandescent lamp was observed by spectrometer experiment.The relationship between incidence angles,diffraction angles,horizontal deflection angles and wavelength was verified,and diffraction patterns under different conditions were obtained.It provides new ideas and directions for the development of many subject areas such as optics and materials science as well as digital storage technology.
