What is the initial state n1 for Balmer series?

For the Balmer series, the initial state n1 is 2 and n2 = 3, 4,…

Balmer series

The Balmer series is the name given to a series of spectral emission lines of the hydrogen atom that result from electron transitions from higher levels down to the energy level with principal quantum number 2.

  • Balmer decided that the most likely atom to show simple spectral patterns was the lightest atom, hydrogen. Angstrom had measured the four visible spectral lines to have wavelengths 656.21, 486.07, 434.01 and 410.12 nm.
  • RH (1/4 – 1/n22)
