et's consider the "parity" operator, Py(x) = 1(-x), (1) which mirror reflects the wavefunction about a = 0. [1pt] What is P2,(x)? ) [1pt] What are the possible eigenvalues of P? ) [1pt] If H = P + V(x) where V(a) = V(-x) then what is [H, P]? ) [1pt] Show that if u(x) is a stationary state of energy E, then so is v(-x). What is the nergy of (-x)? [1pt] Are energy and parity compatible observables in this system
