Atomic Spectra

Using the formula
V=R(1/nsquared - 1/nsquared)
in atomic spectra problems, what does it mean when the initial n is greater than the final n (ex// n=1 transitioning to n=5) and you get a negative value for the frequency of the energy emitted?

You won't get a negative value because the value for (initial) is always going to be lower than (final). When you put those values under a fraction, the previously larger value will become the smaller one, and vice versa.

Let's use your example of 1 and 5:






Hope this helps!
