I'm wondering if the wave function can be a constant in some special cases?(adsbygoogle = window.adsbygoogle || []).push({});

Now I understand that if we have a one dimensional wave function describing the location of a particle (say, along the x-axis), then the wave function can not be a constant. If it was, then it wouldn't be normalizable.

But what if the particle is free to move in a circle? The we have [tex]\psi(\theta) = \psi(\theta + 2 * \pi)[/tex]
