E) that start in the ground state.

Question

Quizplus · Accepted Answer

The four visible lines emitted by hydrogen atoms are known as the Balmer series, and they are produced by electrons that end up in the n = 2 level. The wavelengths of these visible lines correspond to specific energy transitions between higher energy levels and the n = 2 level.
