SUMMARY
The parity of a wavefunction refers to its behavior under spatial inversion, defined mathematically as PΨ(x,y,z) = ±Ψ(x,y,z). The parity operator P transforms the position vector as {\vec r} → -{\vec r}. Wavefunctions can exhibit even or odd parity, where even functions like cos(x) remain unchanged under inversion, indicating symmetry, while odd functions like sin(x) change sign, indicating anti-symmetry. Understanding parity is crucial for analyzing the symmetry properties of quantum systems.
