What is the longest wavelength in the Lyman Series?
A)45.60 nm
B)91.20 nm
C)121.5 nm
D)240.1 nm
E)365 nm

Question

Quizplus · Accepted Answer

The Lyman series corresponds to the emission or absorption of photons in the ultraviolet region that occurs when an electron in a hydrogen atom transitions from an excited state to the n = 1 ground state. The longest wavelength in the Lyman series corresponds to the transition from n = ∞ (an excited state far from the nucleus) to n = 1. This transition is known as the Lyman limit and has a wavelength of 121.5 nm. Therefore, choice C is the correct answer.
