A wave is traveling with a speed v along the x axis in the positive direction. The upper graph shows the displacement y versus the distance x for a given instant of time. The lower graph shows the displacement y versus the time t for any given point x. From the information in the graphs, what is the wave speed v?
A) 8.0 m/s
B) 4.0 m/s
C) 6.0 m/s
D) There is not enough information to solve the problem.
E) None of these is correct.
