"WebNotice that for the ground state, n = 1, l = 0, and m = 0. In other words, there is only one quantum state with the wave function for n = 1, and it is ψ 100. However, for n = 2, we have l = 0, m = 0 l = 1, m = −1, 0, 1. Therefore, the allowed states for the n = 2 state are ψ 200, ψ 21 − 1, ψ 210, and ψ 211. " - State vector- wave function

State vector- wave function

In quantum physics, a wave function is a mathematical description of the quantum state of an isolated quantum system. The wave function is a complex-valued probability amplitude, and the probabilities for the possible results of measurements made on the system can be derived from it. The most common symbols for a wave function are the Greek letters ψ and Ψ (lower-case and capital psi, respectively). WebThis function is expressible as a linear combination of the eigenstates of any observable. Observables represent classical dynamical variables, and when one is measured by a …
