Intensities in the Hydrogen Spectrum. Viewed 81 times 1. To determine the Rydberg's Constant by studying Hydrogen Spectrum. When hydrogen gas at low pressure is taken in the discharge tube and the light emitted on passing electric discharge is examined with a spectroscope ,the spectrum obtained is called the emission spectrum of hydrogen.It is found to consist of a large number of lines which are grouped into different series ,named after the discoverer. This particular series of lines, called the Lyman series, falls in the ultraviolet region of the spectrum because of the large energy changes involved in the transitions from the excited levels to the lowest level. For example, the ($$n_1=1/n_2=2$$) line is called "Lyman-alpha" (Ly-α), while the ($$n_1=3/n_2=7$$) line is called "Paschen-delta" (Pa-δ). The emission spectrum of atomic hydrogen has been divided into a number of spectral series, with wavelengths given by the Rydberg formula.
