(b) In a hydrogen atom, the electron has energy, En = -Eo/n2, where Eo is a constant, and n is the principle quantum number (i.e., the “shell”). For quantum mechanical reasons, n must be a positive integer. For instance, the ground state corresponds to n=1. The first excited state corresponds to n= 2 and so on. In order to determine the value of Eo, a scientist shines photons ("light particles”) of various energies at a cloud of atomic hydrogen. Most of the hydrogen atoms occupy the ground state. A detector records the intensity of light transmitted through that cloud (see Figure 1). Figure 2 is a graph of part of the scientist's data, showing the intensity of the transmitted light as a function of the photon energy. Determine the approximate value of Eo.
