Waves transfering from one medium to another?

For a lab we did, we connected a slinky and a coil spring together so there would be a change in medium. Then, we sent pulses and waves down each spring and observed how the wave changed as it passes from one medium into the other. Here is the question that was asked after:





Each time a wave reaches the boundary between the two springs it is______(partially, totally) reflected and


______(partially, totally) transmitted.





Thanks!
