Practical Examples and Applications for Diffraction and Interference of Lights in Experimental Physics 1

I introduce some experimental topics regarding diffraction and interference of light penetrating a single and double slit. The physics of diffraction and interference can be explained by the superposition of waves in direct space with a slight phase difference, which is an important concept in the field of not only applied physics but also condensed matter physics and cosmology. In the Faculty of Science, Kanagawa University, subjects on wave physics are systematically taught to first-year to third-year students in the class of experimental physics. I show some examples of Fraunhofer diffraction of light by a single and double slit, covered in the Experimental Physics 1, and finally expand to Fresnel diffraction as an advanced subject.Departmental Bulletin Paper教育論文departmental bulletin pape
