Wave Propagation

An HTML 5 app to observe wave propagating in the positive and negative x-directions.
Two waves $y_1 = A\sin(\omega t - b x)$ (purple) and $y_2 = A\sin(\omega t + b x)$ (red) propagate in different directions. The wave propagation is due to the terms $\omega t - b x$ and $\omega t + b x$.
