1. Calculate the frequency, in Hz, for the red spectral line of hydrogen with a wavelength of 656 nm. (3 s.f.) 2. Determine the value of 1/λ, with λ in meters, for the red spectral line above (yes, it is that easy – 1 divided by lambda. Be careful of the conversion to m–1unit). 3. The Rydberg equation can be thought of as 1/l= (Ryd)(transition value). Determine the “transition value” from n = 4 to n =2. (Don’t determine the energy, nor the wavelength,...

Emission line spectra for various elements are shown in Table 1
and Table 2 shows the wavelengths for various colors. Remember, E =
h*c/?, where E is energy, h = 6.626*10-34 J*s, c =
3.00*108 m/s, ? is the wavelength, and 1 m =
109 nm.
