(b) Find the longest and shortest wavelengths in the Lyman series for hydrogen. Paschen series—Infra-red region, 4. This is the only series of lines in the electromagnetic spectrum that lies in the visible region. The Balmer series, or Balmer lines in atomic physics, is one of a set of six named series describing the spectral line emissions of the hydrogen atom. The Balmer equation could be used to find the wavelength of the absorption/emission lines and was originally presented as follows (save for a notation change to give Balmer's constant as B): In 1888 the physicist Johannes Rydberg generalized the Balmer equation for all transitions of hydrogen.
