Question

The answers says that the distance travelled is 0.30m? why is that? Could you mark in the drawing? What does this two wave lines mean?How can you see that the displacement is negative and that the direction is to the left?

4. A longitudinal wave is travelling in a medium from left to right. The graph shows the variation with distance x of the displacement y of the particles in the medium. The solid line and the dotted line show the displacement at t-0 and t-0.882 ms, respectively 4 2 1.0 .5 2.0 2.5 3.0 2 -4 The period of the wave is greater than 0.882 (C) A displacement to the right of the
