The above simulations show disturbances on two identical strings (position is in centimeters and time is in seconds).
At t=2.5 seconds, describe the superposition of each of the three pairs of waves.
Red - Their superposition has a large peak, a depression, and then another large peak.
Green - Their superposition is zero.
Blue - Their superposition has a large peak on the left and a smaller trough on the right.
