Answer 2

The four other spectral line series, in addition to the Balmer series, are named after their discoverers, Theodore Lyman, A.H. Pfund, and F.S. Brackett of the United States and Friedrich Paschen of Germany. The Lyman series lies in the ultraviolet, whereas the Paschen, Brackett, and Pfund series lie in the infrared.
