Question

Quizplus · Accepted Answer

The longest possible wavelength corresponds to the smallest possible energy transition, which occurs between the n=2 and n=1 energy levels in the hydrogen atom. However, theoretically, as the energy levels get very close to each other at very high n, the energy difference between them becomes infinitesimally small, leading to an infinitely long wavelength. Therefore, there is no upper limit to the wavelength that a hydrogen atom can emit.
