This article intends to show three methods in gases spectroscopy for wavelengths of an emission spectrum of the hydrogen atom a ranging precision between 0.19 % and 0.95 %, and an accuracy between 4.6 % and 0.45 %; in the first two methods reference lines defined for two noble gases and mercury vapor are used, which allows adequate calibration for Bunsen-Kirchhoff spectrometer and a configuration using a diffraction replica of 500 lines/mm for a first pattern of a not symmetric pattern, in the third method electromagnetic diffraction theory of wavelength is used to determine wavelengths emission of each spectral line observed in a first order symmetric diffraction pattern. Subsequently the validity of more precise and accurate method being verified measure out of the Rydberg constant for three lines of emission in hydrogen with a precision of 0.34 %.
