A sample of atomic hydrogen gas is excited such that electrons populate the \(n = 4\) energy level. Photons emitted when these electrons transition directly from the \(n = 4\) level to the \(n = 1\) ground state are directed onto the cathode of a photoelectric apparatus, where the cathode material has a work function of \(4.75 \text{ eV}\). The energy levels of the hydrogen atom are \(E_1 = -13.60 \text{ eV}\), \(E_2 = -3.40 \text{ eV}\), \(E_3 = -1.51 \text{ eV}\), and \(E_4 = -0.85 \text{ eV}\). What is the stopping potential required to prevent the ejected photoelectrons from reaching the anode?
