Calculate the longest wavelength for the transition in the Paschen series of `He^`

Find the wave number for the longest wavelength transition in the Balmer series of atomic hydrogen.

Calculate the wavelength for the emission transition if it starts from the orbit having radius 1.3225 nm and ends at 211.6 pm. Name the series to which this transition belongs and the region of the spectrum.

The observed wavelength in the line spectrum of hydrogen atom were first expressed in term of a series of johann jakob Balmer a series teacher Balmer's empirical formula is 1/lambda=R_H(I/2^2-I/N^2) ________ n ge 3 , R_H=109678cm^-1 is Rydberg constant. Niele Bohr derived this expression theoretically in 1913 the formula is generalized to any uni-electronic species. Calculate the longest wavelength in the Balmer series of singly ionized He^+
