Balmer Series
Balmer Series The Balmer series is a set of spectral lines of the hydrogen atom that result from electron transitions from higher energy levels (n ≥ 3) to the second energy level (n = 2). These transitions emit light in the visible spectrum. The Balmer series includes the following lines, named after their discoverer, Johann Balmer: H-alpha : Transition from n = 3 to n = 2, red light with a wavelength of about 656 nm. H-beta : Transition from n = 4 to n = 2, blue-green light with a wavelength of about 486 nm. H-gamma : Transition from n = 5 to n = 2, violet light with a wavelength of about 434 nm. H-delta : Transition from n = 6 to n = 2, violet light with a wavelength of about 410 nm. These lines can be observed in the emission spectrum of hydrogen and are crucial in the study of atomic structure and quantum mechanics.
