BEATING PHENOMENON IN STANDING WAVES

In the information age, resources are abundant and knowledge is rapidly updating, but the basic physical concepts and theoretical principles remain immutable. How to transfer mundane physical formulas and complicated physical laws into intuitive and dynamic demonstrations during the classroom teaching process, as well as igniting students' enthusiasm to stimulate their in-depth thought have become a problem and challenge faced by Collage Physics. In this paper, we take “the composition of multiple vibrations and travelling waves” as an example, using Matlab software to build a visual physics demonstration platform, dynamically demonstrating the physical processes of beats and standing waves. By slightly adjusting parameters such as amplitude, frequency, and wave speed, the evolution laws and visual analysis of amplitude, phase, and energy ofconventional standing waves after the superposition of beat effects are explored. Further, an interactive operation interface is introduced to display the visualization of complex motion and sound output of virtual demonstration experiments. These pedagogical endeavors can greatly enhance students' spatial imagination with expand threedimensional scientific thinking. Simultaneously, such teaching attempts encourage and guide students to search for related literatures and independent practice, which further promotes their engagements in freely exploring a broader array of physical phenomena in the natural world.
