## Two Dimensional Well Exercise #3

#### Please answer the following 2 questions
regarding the Physlet:

#### Description

Shown is the wave function for two non-interacting and identical
(or indistinguishable) particles in a one-dimensional infinite square well (We
can call them particles "1" and "2"). One
dimension (x) represents one particle and
the other side (y) represents the other particle. You may click-drag around the
axes and use a shift-click-drag to zoom.

#### Questions

- Given a wave function that looks like: y(x
_{2},
x_{1}) = y_{1}(x_{2})y_{2}(x_{1}),
what do the ones and twos (the subscripts) mean?
- Which probability density represented above represents a symmetric
state and
which one an anti-symmetric state.
