wavelength range

[Sisam Bhattarai 2C]

Finding the number of spectral lines ( eg. n=5), I know you use n-1 to get it ( answ: 4 spectral lines). However, when finding its wavelength radiation, I am unsure what formula correlates with it and if it uses the lyman structure. Do I use 4 and 1 somehow to calculate it since those are the highest and lowest spectral lines when n+5. Thank you!

To determine the wavelegnth range you would find the wavelength from the largest spectral from n=5 to n=1 with the equation v=R[1/n1^2-1/n2^2]. Then you would do the same for the smallest spectral line from n=5 to n=4. Then you would take these two wavelengths and find the difference between them to find the range.

You'll be using the Rydberg equation to find the frequency of n=5 to n=1 then to n=5 to n=4. Then convert these to wavelengths in meters and finally to nanometers.
