Question

Suppose a scientist directed a single photon toward an isolated hydrogen atom. The photon was absorbed and an electronic transition took place (ni=1, nf=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).

Question 5 options:

The photon emitted first will have less energy than the photon emitted second.

Both of the emitted photons will have identical energy, each 1/2 the energy of the initial photon.

The photon emitted first will have greater energy than the photon emitted second.

The detector must be broken. It is impossible for one photon to be absorbed, and later two photons to be emitted from the same atom.
