Abstract: Wave is a universal physical phenomenon. Due to the abstraction and difficulty in direct observation, two-dimensional waves have not been elaborately and deeply explained in most textbooks. Based on the Python, we develop a program which can visualize the two-dimensional mechanical wave and standing wave. The program also possesses the function of human-computer interaction, and can output the image of two-dimensional standing wave, standing wave vibration animation and mechanical wave propagation animation with the input parameters. The computational simulation can assist to visualize the Abstract： theories, and help students’ understanding of the properties of two-dimensional standing waves, cultivating students’ thinking ability and imagination ability, greatly improving the teaching effect, and laying a foundation for students’ future study and research work.
