How many Balmer spectral lines will be obtained when the excited electrons return from 8th shell to 2nd shell?

How many Balmer lines in the spectrum will be observed when electrons return from 7^(th) shell to 2^(nd) shell ?

The observed wavelengths in the line spectrum of hydrogen atom were first expressed in terms of a seriesby Johamn Balmer a swiss teacher. Balmer.s empirical formula is : (1)/(lambda) = R_(H)[(1)/(2^(2))-(1)/(n^(2))]n=3,4,5 …. R_(H) = 109678 cm^(-1) is the Rydberg constant How many lines in the spectrum will be observed when electrons return from 7^(th) shell to 2^(nd) shell ?

The observed wavelengths in the line spectrum of hydrogen atom were first expressed in terms of a series by Johann Jakob Balmer, a Swiss teacher. Balmer's empirical formula is (1)/(lambda) = R_(H)[(1)/(2^(2)) - (1)/(n^(2))] = n = 3, 4,5… R_(H) = 109678 cm^(-1) is the Rydberg constant. Niels Bohr derived this expression theoretically in 1913. The formula is a generalised to any on electron atom/ion. How many lines in the spectrum will be observed when electrons returns from 7th shell to 2nd shell ?

How many lines in the spectrum will be observed when an electron returns from 7th shell to 2nd shell?

How many spectral lines can be obtained during the de-excitation of electron of hydrogen from 'O' shell to the most stable state ?
