![Ocean waves with a wavelength of 9.2 m and velocity v = 1.20 m/s can be modeled using the equation shown, y(x, t) = (0.79 m)sin[(0.683 m−1)(x − vt)]. Note that x and y are in meters and t is in seconds. (a) Choose the graph of y(x, t) at t = 0. (b) Choose the graph of y(x, t) at t = 2.00 s. (c) How has the wave moved between graph (a) and graph (b)? The wave has traveled 2.40 m to the left. The wave has traveled 2.00 m to the right. The wave has traveled 2.40 m to the right. The wave has traveled 2.00 m to the left.](https://www.doubtrix.com/uploads/editor/2080836045OAqVVupieu.png)
