Formula and explanation

Formula: (1)/(λ) = R H Z² ( (1)/(n f²) - (1)/(n i²) ight), where n i > n f. Applicable Conditions: Line spectra of hydrogen atom or hydrogen - like ions. Explanation: Describes the wavelength of photons emitted or absorbed when electrons transition between different energy levels ( n i and n f ). R H is the Rydberg constant.
