Question

Quizplus · Accepted Answer

In population inversion, there are more electrons occupying higher energy levels than lower energy levels. This creates an inverted population distribution, where there are fewer electrons in the lower energy levels that would traditionally occupy them. This condition is essential for laser operation, where a stimulated emission of photons occurs when the population of electrons in the excited state is greater than in the ground state.
