The visible emission lines observed by Balmer all involved nf = 2. Which of the following is the best explanation of why the lines with nf = 3 are not observed in the visible portion of the spectrum? Transitions to nf = 3 emit photons in the ultraviolet portion of the spectrum. Transitions to nf = 3 emit photons in the infrared portion of the spectrum. Transitions to nf = 3 emit photons that are at exactly the same wavelengths...

Hydrogen exhibits several series of line spectra in different spectral regions. For example the Lyman series (nf = 1 in Balmer-Rydberg equation) occurs in the ultraviolet region while the Balmer (nf = 2) series occurs in the visible range and the Paschen (nf = 3), Brackett (nf = 4) and Pfund ( nf = 5) series all occur in the infrared range. What is the shortest-wavelength (in nm) in the Brackett series?

The spectrum of light from heated up hydrogen gas has only a few wavelengths present. These are known as spectral lines. It includes a red line at 656 nm and a blue-violet line at 434 nm. What are the angular separations between these two spectral lines for all visible orders obtained with a diffraction grating that has 4770 grooves/cm? (In this problem assume that the light is incident normally on the grating.) I'm having trouble with this question as I'm...

A. Find 3 spectral lines of Hydrogen in the near-Infrared. (Between 800nm and 1200nm wavelength.) Give the initial and final states for each transition. B. An atom has (bound) electron energy levels at -6.3eV, -4.2eV, and -2.8eV. Show a calculation of all wavelengths that will be emitted if a collection of these atoms are excited. Hint: there will be more than 2.
