Quizplus · Accepted Answer

To determine the wavelength, we need to find the distance between two consecutive peaks or troughs of the wave. We can see from the graph that the distance between two consecutive peaks or troughs in the displacement vs. position graph is approximately 3 meters. Therefore, the wavelength of the wave is 3 meters.
