Question

The figure below shows snapshots of the wave on the string at three instants in time (t1,t2,t3) as the wave travels to the right. The dot painted on the string is indicated at point 1 ti t2 ts t2 t3 Three students argue about which picture is correct. Which do you most closely agree with? Student A: "The bottom picture is correct, because the wave is traveling to the right. Since the wave and the string look exactly the same, the dot must move with the wave to the right." Student B: "The top picture is correct, because the wave is a disturbance of the string, not the string itself. As the wave travels to the right, the string moves up and down. Therefore, the dot moves up and down with the string." Student C: "Neither picture is correct. The string's position is at y-0 at point 1, which means the dot just sits there." O Student A Student B Student C I don't agree with any of them
