The each of the two resonances frequencies in the secondary are caused by the standing waves. You could call them standing wave resonances or wave resonances.
```
```
The wave is reflected at the top end and reflected at the bottom end. At the bottom end the reflected impedance of the primary allows two possible resonances.
```
```
One way to look at the wave resonance is to say that the reflected waves from both the top and bottom are such that they beat and reinforce each other.
