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? A) Yes, two otherwise separate lines would converge into a single more intense line. B) No, but the spacing between the spectral lines would change. C) Yes, two otherwise separate lines would converge into a single less intense line. D) No, but some would then require a prism in order to be seen.
