13) An energylevel diagram for a hypothetical atom is written on the board. a) Determine the frequency of the lowest energy photon that could ionize the atom, initially in its ground state (5 pts) b) Assume the atom has been excited to the state at 10 electron volt. i. Determine the wavelength of the photon for each possible spontaneous transition. (2.5 pts) 11. Which, if any, of these wavelengths are in the visible range? (2.5 pts) c) Imagine an electron drops from the second excited state back into its ground state, and releases a photon. That photon then enters a silicon crystal whose atoms have electron energy levels are described by the quantum oscillator. What would be the necessary frequency w of the oscillator for the incident photon to excite an electron from its ground state (n=0) to the third excited (n-3)? (10 pts)
