Developing physics teaching resources with computer softwares is an important content in the field of contemporary physics teaching．Physics teachers in the new era should master modern computer tools，making them sharp weapons for physics teaching reform and innovation．As an example，it accurately and dynamically simulates several typical wave phenomena in classical physics with the software Mathematica．The series of animations developed in the study are vivid and intuitive，and thus very helpful for learners to establish clear physics images，expand their knowledge of the wave phenomena and deepen their understandings of relevant wave laws，adding rich and colorful teaching resources to physics courses．On the other hand，this study also fully demonstrates the powerful capability and broad application prospect of the software Mathematica in the development of physics teaching resources．
