 I think of it like waves on a string of different materials.  Any time the wave changes medium there will be both reflection and transmission.  If you think of the potential well as just a part of the string that is less dense and a wall as part that is more dense, it makes sense.  Anytime the wave changes potentials, it's like the string changing mediums.  At least that's how i think of it, but i could be missing something too.

+Are there other resources that explain the delta function and the associated limit of a sequence.

+When we have a delta-function barrier, why do we no longer have a bound state?
