Balmer Series: If the transition of electron takes place from any higher orbit (principal quantum number = 3, 4, 5, …) to the second orbit (principal quantum number = 2). This series is called the Balmer Series after the Swiss teacher Johann Balmer (1825-1898) who, in 1885, found by trial and error a formula to describe the wavelengths of these lines. Hey - Teacher - Leave them kids alone and go do some physics.Atomic spectra have been well-known and beautiful for a long time. These lines are emitted when the electron in the hydrogen atom transitions from the n = 3 or greater orbital down to the n = 2 orbital.

He derived the Balmer-Rydberg formula, for the spectral lines of radiation from the hydrogen atom, by invoking the quantum theory and making two postulates [6, 7]. With the Danish physicist Niels…, The Balmer series, discovered in 1885, was the first series of lines whose mathematical pattern was found empirically. Hier machte sich insbesondere der schwedische Physiker Anders Jonas ANGSTRÖM (1814 - 1874) einen Namen. The model also explains the Balmer formula for the spectral lines of hydrogen. H-alpha is the red line at the right. I don't think the question relates directly to the Balmer Series, but I could be wrong. These lines are emitted when the electron in the hydrogen atom transitions from the, The electron travels in circular orbits around the nucleus. That number was 364.50682 nm. The question asks which transition will result in the shortest wavelength, so its asking which will result in the highest release of energy.
