Parity operator

[UrbanXrisis]

just wondering... does the parity operator squared give the identity operator?

What, exactly, is the definition of the "parity operator"?

 

[ziad1985]

what would happen if you take a wave function Psi and apply the Parity operator twice?
try it

hehe... so it WOULD be an like the identity operator
