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