16.2 Exercise 19

Consider two waves defined by the wave functions $y_{1} \left(x , t\right) = 0.50 \text{m} \text{sin} \left(\frac{2 \pi}{3.00 \text{m}} x + \frac{2 \pi}{4.00 \text{s}} t\right)$ and $y_{2} \left(x , t\right) = 0.50 \text{m} \text{sin} \left(\frac{2 \pi}{6.00 \text{m}} x - \frac{2 \pi}{4.00 \text{s}} t\right) .$ What are the similarities and differences between the two waves?
