Where Did The Operator Come From? For Momentum, Why Is It Different From Just Ρ? |
|
Answer» The OPERATOR is a function which, when acting on Ψ in the probability integral, produces an expectation value for that QUANTITY In the Schrodinger REPRESENTATION. The operator for X is just x, for x2 it is just x2. But for momentum we have to find a way to WRITE Ρ in terms of x or t, so that we can do the integral.
