| Essentially, what I get from this is that this deals with the probability of a particle being able to get out of a well. The more energetic a particle is the greater the probability it has of escaping from the well. So if a particle does not have the energy to make it through the barrier then it will be reflected back into the well (trapped). Of course, that is not to say it will never be able to get out. Although, it energy is less than the barrier it can still escape by means of tunneling. | Essentially, what I get from this is that this deals with the probability of a particle being able to get out of a well.

| | 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? |
