Question 2

A spectrometer is used to study electron transitions in a vapour. Radiation transfers a total of 3.0 × 10-16 J to 500 electrons, moving each electron from orbit L to orbit N.

Each electron later returns to orbit L through orbit M. The transition from orbit N to orbit M emits 2.2 × 10-19 J per electron.

What energy is emitted by one electron during the transition from orbit M to orbit L?
