### Lyman and Balmer series.

Will we need to know about the Lyman or Balmer series for the test?

I believe we might need to know the relative wavelengths associated with each of the series. For example, since the Balmer series includes the visible light spectrum it has relatively greater wavelengths than that of the Lyman series (which contains the ultraviolet spectrum). This general information will help us in problems in which we are asked to find the values for "n1 and n2" or the initial and final energy levels. In Lyman series the principal quantum number for the lower energy level involved, n1, is 1 whereas it is 2 for the Balmer series.

Should we know the approximate numbers of the different wavelengths?

Yes, that will be helpful, but as long as you understand the concept and know what higher/lower wavelengths mean, you should be fine. For instance, a microwave will have a long wavelength, low frequency, and low energy, whereas an x-ray will have a short wavelength, higher frequency, and higher energy. Knowing those concepts, you can figure out what the formulas are saying and solve the problems easier.

I guess we don't need to.
