A wave is travelling on a string in the x direction. The two graphs show the variation with distance x of the displacement y of the string. Graph 1 corresponds to time t = 0 and graph 2 to time t = 0.20 s. Graph 1 (t=0) direction of travel 1.5- y/ mm 1.0- 0.5- 0.0- |10 x/ cm -0.5 -1.0- -1.5- Graph 2 (1=0.20 s) direction of travel 1.5 y / mm 1.0- 0.5 0.0- 10 x/ cm -0.5 -1.0- -1.5 The period of the wave is longer than 0.20 s.
