Bound States of Infinite Square Well

  1. Jul 6, 2014 #1
    Hi all,
    So I was recently set straight on the fact that bound state does *not* necessarily mean E<0 but rather is the statement that E<V(+/- infinity). So how do we apply this definition to the infinite square well where the potential at +/- infinity vanishes, and yet the bound states have positive energy?
    Thanks in advance!

    The potential of the infinite square well at infinity is infinity?

    oh god, yes of course. I was confusing it with the w.f. vanishing. Was very tired when i posted! thx
