What is the wavelength of a photon emitted from a hydrogen atom when an electron drops from the n=6 to the n=1 level? Hint: use the Rydberg formula.

109.351 nm
67.8999 nm
222.453 nm
0.0937901 nm
93.76 nm
131.226 nm

Please select all the following statements that are true concerning absorption and emission spectra. An emission spectrum is created when a sample of excited gas emits particular frequencies of light. By looking at each spectrum, we can see that the electrons move between discrete energy levels, resulting in specific wavelengths associated with each transition. An absorption spectrum is created when a sample of excited gas emits particular frequencies of light. If the energy of the electron is increasing, then there must be an emission of light energy. Conversely, if the energy of the electron is decreasing, then there must be an absorption of light energy. For a particular chemical, its absorption and emission spectra show the same discrete line patterns.
