A Cartesian graph showing vertical displacement y in centimeters on the vertical axis against horizontal position x in meters on the horizontal axis. The horizontal axis ranges from 0.0 to 0.8 meters with major tick marks every 0.1 meters labeled 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8. The vertical axis ranges from -4.0 to +4.0 centimeters with tick marks at -4.0, 0.0, and +4.0. A smooth sinusoidal curve starts at (0.0, 0.0), rises to a crest at (0.1, +4.0), crosses zero at (0.2, 0.0), reaches a trough at (0.3, -4.0), crosses zero at (0.4, 0.0), reaches a crest at (0.5, +4.0), crosses zero at (0.6, 0.0), reaches a trough at (0.7, -4.0), and ends at zero at (0.8, 0.0). No other labels, lines, text, or axes appear.
Displacement \(y\) versus position \(x\) for a wave at time \(t = 0\text{ s}\).
A transverse periodic wave travels along a stretched string. The snapshot graph shows the vertical displacement \(y\) of the string as a function of horizontal position \(x\) at time \(t = 0\text{ s}\). If the frequency of the wave generator is \(5.0\text{ Hz}\), what is the speed of the wave?
