The “Spectrum of Atomic Hydrogen,” Experiment 21 in Advanced Physics with Vernier–Beyond Mechanics, is a classical investigation of the Balmer Series of the hydrogen spectrum. In this experiment, students use the Vernier Emissions Spectrometer to determine the wavelengths of the visible lines of excited hydrogen gas, relate photon energies to energy level transitions, and.

explanation for the discrete atomic lines became clear. In this laboratory you will measure the wavelengths of the discrete emission lines from two elements – hydrogen and sodium – to determine the energy levels in the hydrogen-like atoms. Hydrogen Spectrum The hydrogen atom is the simplest atom: it consists of a single proton and a single electron.

The spectrum appears in a series of lines called the line spectrum. This line spectrum is called an atomic spectrum when it originates from an atom in elemental form. Each element has a different atomic spectrum. The production of line spectra by the atoms of an element indicate that an atom can radiate only a certain amount of energy.

Atomic Spectra. The dark lines in the absorption spectrum correspond to the wavelengths of specific colours of photons needed by the electron to jump from lower to higher energy levels. Each dark line is because the wavelength is absorbed or bright line because the wavelength is emitted represents an energy level such as n = 1, n = 2, n = 3, in the orbital space.
