So, for example, we could talk about the n equals 2 state, so that's this state here, and it's also what we could call the first excited state. So we have the ground state, and if we excite an electron into the next closest state, we're at the first excited state, or the n equals 2 state.

例如，我们可以考虑n等于2的状态，它在这里，它也被称作是第一激发态,我们有基态，如果我们把一个电子,激发到它最近邻的态,那就是第一激发态，或者n等于2的态。
