Hydrogen is found to emit light with wavelengths falling in systematic patterns called "series": Lyman, Balmer, Paschen, Brackett, and Pfund are the first five. If we observe a wavelength of 656 nm (red), what line of what series is it? The first line of a series is the one with the longest possible wavelength. o o o e First line of the Lyman series First line of the Balmer series Second line of the Paschen series Second line of the Balmer series
