05 Question (4 points) When a hydrogen atom absorbs a photon of electromagnetic radiation (EMR), the internal energy of the atom increases and one or more electrons may be energized into an excited state. The release of this extra energy as the excited state electron transitions back to a lower energy state results in the emission of a photon. These energy changes are responsible for the emission spectrum of hydrogen (shown below) and are described by the Bohr equation. AE...

Hydrogen spectrum tube a. The light emitted in a hydrogen spectrum tube comes from isolated hydrogen atoms excited by electricity. Is the spectrum of the light emitted by isolated atoms discrete or continuous? b. The spectrum of hydrogen is described by Rydberg's formula: , where R = 1.097 x 107m1 Based on Rydberg's formula, identify the electronic transitions (n + n) that correspond to each of the colored photons that you saw and their expected wavelengths. Compare them to the...
