The parity of a wavefunction is a property that describes how the wavefunction changes when its coordinates are inverted. It can be either even (+1) or odd (-1).
The parity of a wavefunction is determined by examining the transformation of its coordinates under inversion. If the wavefunction remains unchanged, it is even, and if it changes sign, it is odd.
The parity of a wavefunction is important in understanding the symmetry of physical systems. A system with even parity is symmetric under inversion, while a system with odd parity is asymmetric.
The main difference between even and odd parity is their behavior under inversion. Even parity wavefunctions remain unchanged, while odd parity wavefunctions change sign when coordinates are inverted.
No, a wavefunction can only have one parity. However, a wavefunction can be a linear combination of even and odd functions, resulting in a mixed or undefined parity.
