- I am confused about why the two seem to be approached the same in all the solutions I have seen
Hi everyone!
This is the first time I'm posting on any forum and I'm still rather unsure of how to format so I'm sorry if it seems wonky. I'll try my best to keep the important stuff consistent!
I am working on infinite square well problems, and in the example problem:
V(x) = 0 if: 0 ≤ x ≤ a
∞ : otherwise
H`ere it is obvious that one should take ψ(a)=ψ(0)=0 and solve.
In the next example problem, however, the boundaries are shown as follows:
V(x) = 0 if: -a < x < a
∞ : otherwise
Here potential is zero if x is between (-a) and (a) but not when x is equal to (-a) or (a).
However, in the solution, the author does the same thing, making ψ(-a)=ψ(a)=0
The conditions, however, do not seem to allow this.
What am I missing?
Thank you!
