A string is connected at one end to a vibrating reed and on the other to a weight pulling the string tight over a pulley. At the time t = 0 a photograph of the string looks like the picture at the left below. The wave is then observed to grow in amplitude, reaching a maximum of 3 cm at t = 0.02 sec. It then shrinks in amplitude, and then at time t = 0.06 sec appears flat, as shown in the picture to the right below.
Each box in the grid has a side of 1 cm.
