Consider the various frequencies of the three photons emitted from the following three individual electron transitions in the figure below: n=3 to n=2; n=2 to n=1; n=3 to n=1. These transitions would produce three spectral lines in a spectroscope. If the energy spacing between the levels were equal, would this affect the number of spectral lines?

Question

Quizplus · Accepted Answer

If the energy spacing between the levels were equal, the three spectral lines would have the same frequency difference between them. This means that the difference between the frequencies of the spectral lines would be constant, and two of the lines would converge into a single more intense line. This is known as a doublet. The remaining line would still be separate and distinct. Therefore, the correct answer is A.
