Light of wavelength 411 nm is observed from a hydrogen discharge.What transition produces this emission? The energy of the n = 1 level is -13.6 eV.

Question

Quizplus · Accepted Answer

The wavelength of the emitted light can be calculated using the Rydberg formula, 1/λ = R(1/n1^2 - 1/n2^2), where R is the Rydberg constant and n1 and n2 are the initial and final energy levels of the electron in the hydrogen atom. Solving for n1 and n2, we get n1 = 6 and n2 = 2. This corresponds to the Balmer series, and the transition is from the n = 6 to n = 2 energy level, which produces the observed wavelength of 411 nm. Therefore, the correct choice is B.
