Interactive E-Modules as Teaching Materials on Diffraction and Interference Materials: A Feasibility Test

The selection of learning teaching materials must be carried out as needed and can also utilize technology as a means of making interesting teaching materials. One of the learning teaching materials that can be used to easily understand the concepts of diffraction and interference and utilize technology is an interactive e-module equipped with learning videos. This is because learning about diffraction material and interference with physics requires visualization to improve students' understanding of the material. The research method used is Research and Development or R&D (Research and Development) with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. Research and development of education (research and development) aims to produce new products through the development process. In this study, there was a limitation of steps from five steps to four steps to due diligence according to development needs. The results showed that the interactive e-module on the diffraction and interference material made by the researcher was suitable for use
