The Balmer series results from transitions of the electron in hydrogen in which the electron ends at the $\mathrm{n}=2 n=2$ energy level. Using the Rydberg formula for the Balmer series, calculate the wavelengths of the photons emitted in the transitions that end in the $\mathrm{n}=2 n=2$ level and start in the energy levels that correspond to $n$ equal to 3 through 6 and indicate the initial and final levels of the transition corresponding to each wave length. State whether each wavelength is visible (380 to $750 \mathrm{~nm}$ ), ultraviolet (shorter than $380 \mathrm{~nm}$ ), or infrared (longer than $750 \mathrm{~nm}$ ).
The visible emission lines observed by Balmer all involved $n_{f}=2 .$ (a) Explain why only the lines with $n_{f}=2$ were observed in the visible region of the electromagnetic spectrum. (b) Calculate the wavelengths of the first three lines in the Balmer series - those for which $n_{i}=3,4,$ and $5-$ and identify these lines in the emission spectrum shown in Figure 6.11 .
There are four spectral lines in the visible range for Hydrogen: Wavelength (nm): 410.2 434.0 486.1 656.3 These four lines comprise the Balmer Series. Each line corresponds to a transition that ends at n1 = 2. For the red line (656.3 nm), this corresponds to what value of n2?
