The medium only determines the speed of the wave it does not destroy any portion of the wave nor does it generate anything.The information is conserved.Imagine you have two connected wires with different densities. If you send mechanical pulse you will see that the speed and length change as it passes from one wire to the other but the pulse will not disappear or be split into multiple pulses.
