Balmer Lines in the Spectrum of a Star This portion of the spectrum of the star Vega in the constellation Lyra (the Harp) shows eight Balmer lines, from Hα at 656.3 nm through Hθ (H-theta) at 388.9 nm. The series converges at 364.6 nm, slightly to the left of Hθ. Parts of this image were made using ultraviolet radiation, which is indicated by the highlighted U in the wavelength tab.
