What is the longest wavelength in the Balmer series?
A) 240 nm
B) 328 nm
C) 365 nm
D) 820 nm
E) 656 nm

Question

Quizplus · Accepted Answer

The Balmer series in hydrogen spectrum corresponds to transitions of an electron from higher energy levels (n > 2) to the n = 2 level. The longest wavelength corresponds to the smallest energy difference, which is the transition from the n = 3 level to the n = 2 level. This transition gives a wavelength of approximately 656 nm.
