Ocean waves with a crest-to-crest distance of 10.0 m can be described by the wave function
y(x, t) = (0.800 m) sin[0.628(x - vt)] where v = 1.20 m/s. (a) Sketch y(x, t) at t = 0. (b) Sketch y(x, t) at t = 2.00 s. Note that the entire wave form has shifted 2.40m in the positive x direction in this time interval.
