You have a cold gas of atoms, and you observe that if you shine light consisting of photons with energy 10 eV through the gas, some free electrons are observed, implying that a photon of this energy is able to ionize an atom in the gas. (a) If you find that the emitted electrons from the gas have a kinetic energy of 1 eV, what is the ionization energy of the cold atom? Your answer should be in eVA) Now you shine light with a continuous energy distribution and you observe absorption lines at the following photon energies: 1eV, 3eV, 4eV, and 7eV. Using the information from the two experiments described, select the energies that correspond to all the energy levels of this atom. Hint: Similar to potential energy, the absolute values of the energy levels are arbitrary to a constant, but the difference in energies between levels is not. Follow the convention that the ground state energy (the lowest energy state) is the negative of the ionization energy and base your other answers around this. B) Now you turn off the light and run a beam of electrons through the gas. The kinetic energy of the electrons is 3.5 eV. Collisions of the electrons in the beam with the atoms in the gas exite the atoms to states above the ground state. Select all the possible energies of the emitted photons from this gas.
