Question

what do you mean by 'statinary state'? (1)​

Answer 1

ANs:-

• A stationary state is a quantum state with all observables independent of time.It is also called energy eigenvector, energy eigenstate, energy eigenfunction, or energy eigenket. It is very similar to the concept of atomic orbital and molecular orbital in chemistry, with some slight differences explained below.

Answer 2

Answer:

A stationary state is a quantum state with all observables independent of time. It is an eigenvector of the energy operator (instead of a quantum superposition of different energies).
