atomic spectrum

Calculate the energy emitted when electrons of 1.0 g 1 of hydrogen transition giving spectrum lines of the lowest in the visible regain of its atomic spectrum R_(H) = 1.1 xx 10^(7) m^(-1) , c= 3 xx 10^(8) m s^(-1) and h = 6.62 xx 10^(-34) J s

Calculate the wavelength of the two spectral lines with the longest wavelengths (called the first two lines ) in the visible region of the atomic spectrum of hydrogen, Strategy: Use Balmer's formula, Eq. to calculate the wavelength of visible lines in the atmoic emission spectrum of hydrogen. To calculate the wavelengths of the first two lines, used the two smallest allowed integers, n = 3 and n =4 , in the Balmer formula because lambda is inversely related to n .

Which of the following links lines of the H-atom spectrum belongs to the Balmer series ?

The first emission line in the H-atom spectrum in the Balmer series appears at:
