What is the nergy difference ( in kJ `mol^(-1)`) between the first and second shell fo H-atom if the first emission in the Lyman series occurs at ` lambda = 121.5` nm ?

Calculate the Rydberg constant R if He^(+) ions are known to have the wavelength difference between the first (of the longest wavelength) lines of the Balmer and Lyman series equal to Delta lambda = 133.7nm .

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

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

What hydrogen-like ion has the wavelength difference between the first lines of the Balmer Lyman series equal to 59.3nm ?

What hydrogen-like ion has the wavelength difference between the first lines of the Balmer Lyman series equal to 59.3nm ?

The wave number of the first line in the Balmer series of hydrogen is 15200 cm^(-1) . What would be the wavenumber of the first line in the Lyman series of the Be^(3+) ion?

What will be the ratio of wavelength of the first line to that of the second line of paschen series of H - atom ?
