SUMMARY
In quantum mechanics, an operator A represents a physical observable, with eigenstates, eigenvalues, and eigenfunctions being fundamental concepts. The eigenfunction, denoted as 'f', satisfies the eigenvalue equation Af = λf, where λ represents the eigenvalue. The Hamiltonian operator, which corresponds to the total energy of the system, acts on the eigenfunction to yield a constant multiple of itself, indicating that solutions consist of an infinite set of eigenfunctions and associated energy eigenvalues, indexed by quantum numbers. Understanding the space on which operator A acts is crucial for defining these terms accurately.
