The wavelengths in the visible spectrum of hydrogen analyzed by Balmer are the result of transitions from one of the higher energy orbits into the n = 2 orbit. The Paschen, Brackett, and Pfund series of lines in the infrared spectrum of hydrogen result from electrons dropping into the n = 3, n = 4, and n = 5 orbits, respectively.

This transition to the 2nd energy level is now referred to as the "Balmer Series" of electron transitions. Johan Rydberg use Balmers work to derived an equation for all electron transitions in a hydrogen atom. Here is the equation: R= Rydberg Constant 1.0974x10 7 m-1; λ is the wavelength; n is equal to the energy level (initial and final) If ...

Q5. The diagram below shows the lowest three energy levels of a hydrogen atom. (a) An electron is incident on a hydrogen atom. As a result an electron in the ground state of the hydrogen atom is excited to the n = 2 energy level. The atom then emits a photon of a characteristic frequency.

The nuclear transition resulting in the emission of a positron is illustrated below. The transition energy is shared between the positron and a neutrino. Diagram of a Transition That Produces Positron Radiation. In this transition a proton is converted into a neutron as the positron particle is formed.
