Identify the initial and final states if an electron in hydrogen emits a photon with a wavelength of 656 nm. Enter your answers numerically separated by a comma.
Consider the Balmer series discussed in the book (and Prof. Scherer's lecture notes), where the
frequencies are given by:
x (3.29 × 1015 s-1)
n = 3,4,5, ..
v =
Let us focus only on the spectral lines and transitions corresponding to the Balmer series.
a) Suppose the Balmer series of hydrogen is studied using a Franck-Hertz experiment.
What is the threshold voltage required for n=3? How about n=4?
b) The Lyman Series frequencies are given by v = |1- x (3.29 x 1015 s-1). Describe
what is different about these two series of emission frequencies of photons from the
hydrogen atom? That is, what distinguishes one series from the other? (Hint: it may help
to think about the Bohr model interpretation of transitions.)
Derive the rn, vn and En the quantized parameters for a hydrogen-like atom with a number of protons that you will keep in your derivation of the answers as Z.
Note:1) An example of the situation would for instance He+ with one single electron left to orbit the nucleus of Helium or Li++ with one single electron left to orbit the nucleus of Lithium.
