Question

ote that the taming euge was initially 8.0 m away from x 8.0 m and needed 4.0 s to travel that distance at 2.0 m/s. The displacement at x = 8.0 m returns to zero at 1 4.0 s and remains zero for all later times. This informa- tion is all portrayed on the history graph of FIGURE 20.8. STOP TO THINK 20.2 The graph at the ri wave traveling to the right at a speed of 2.0 m/s. Which is the history graph of this wave at x = 0 m? ght is the history graph at x = 4.0 m of a Ay (cm) The wave at x 4.0m r (s) 0 24 6 8 10 12 Ay (cm) Ay (cm) Ay (cm) Ay (cm) t (s) r (s) r (s) r (s) 0 2 4 6 8 10 12 0 246 8 10 12 02 0 2 4 6 8 10 12

Answer #1

option(b) is correct.

Wave is moving at 2m/s so at x =4 m , 2 sec has passed. In a snapshot 2 sec before leading edge of wave would be at t=6.
