Question

Suppose a scientist directed a single photon toward an isolated hydrogen atom. The photon was absorbed and an electronic transition took place (n_i=l, n_f=3). Later, the scientist checked the detector and noted that signal from two emitted photons had been recorded. Which statement best describes this scenario? (Suggestion: Drawing a representation of the Bohr model, or returning to the simulation, can help your analysis). Only one of the emitted photons will be in the visible-light region of the electromagnetic spectrum. The total energy of the emitted photons is less than the energy of the absorbed photon. The experiment is flawed. There should have been more than two photons emitted. Both of the emitted photons will have identical energy, each 1/2 the energy of the initial photon.

Explanation / Answer

The statement which best describes this scenario would be,

- Only one of the emitted photons will be in the visible region of the electromagnetic spectrum.
