The model used to demonstrate the propagation of waves in one dimension is shown in Figure 3. The source is placed at the center and the signal is propagated in both directions from the source. This model is symmetric and is homogeneous. No reflected waves will be generated and this wave is plotted at time equals 2.0 seconds as displayed in Figure 4.
