In the figure below is shown a picture of a string at a time t1. The pieces of the string are each moving with velocities which are indicated by arrows in the picture. (The vertical displacements are small and don't show up in the picture.)
Below are shown five graphs which could give the shape of the string at the instant for which the velocities are displayed above. (Note: the vertical scale magnifies the displacement by a factor of 100.)
For each of the cases A - E choose whether the string that has that position graph and the velocity pattern at the top is moving as a: (L) left-traveling wave (R) right traveling wave (S+) a standing wave increasing in amplitude (S-) a standing wave decreasing in amplitude (N) none of the above.
1. For graph A: ---Select--- L R S+ S- N
2. For graph B: ---Select--- L R S+ S- N
3. For graph C: ---Select--- L R S+ S- N
4. For graph D: ---Select--- L R S+ S- N
5. For graph E: ---Select--- L R S+ S- N
