Abstract
The aim of this study is to demonstrate 1D Gaussian wave packet propagation and 2D wave deflection in a square membrane using the excel interactive spreadsheets with the Visual Basic for Application (VBA) programming. It is based on the analytic solution of Gaussian packet wave propagation in x direction and 2D wave propagation in square membrane. The vibration modes of 2D wave are determined by using differential equation and initial conditions. The simulation based on the spread sheets functions and facilities has been explored to show the 1D and 2D moving objects in transitional processes. This instrument is very useful both in teaching activity and learning process of wave physics. Visualizing of the vibration of wave in the square membrane show a very clear manner of m and n vibration modes of the wave. There for, in the Gaussian packet waves with the superposition processes between those waves show that the amplitude shifted in a different manner.
