Main Question or Discussion Point
I am new to quantum mechanics so I am just trying to get an understanding of the infinite square well. I have been reading a lot of material and I see a lot of times that the barriers of the well say -L/2 and L/2. I know that outside the well to the left is -infinity and to the right is infinity. Does the left barrier always have to be zero? The examples I am finding all have it that when. Can you just arbitrarily pick the width of the well? Also, the result you get from the well is the probably the particle is going to be in that spot inside the well, correct? Does that mean if I have my barriers at 1 and 2 the result will be the probably that it will be between 1 and 2 or will it actually give me where between one and two it is going to be? Thanks for all your help in advance!
