Imagine That the Energy Levels of a Certain System Are $\sqrt{n}$

Multiple Choice

Imagine that the energy levels of a certain system are proportional to $\sqrt{n}$ , where $n=1,2,3, \ldots$ Imagine that for some reason, only transitions such that $\Delta n=1$ are physically possible. In a spectrum chart (like the one shown in figure Q11.2) the emission lines produced by this system

A) Get closer together (in energy) as we go to the right.
B) Are evenly spaced (in energy) .
C) Get farther apart (in energy) as we go to the right.
