Consider the photoelectric effect experiment below, where the plate on the left is being stimulated by photons, and the plate on the right is at a positive voltage. Answer the questions below on your show your work sheet. No answer in canvas is required for full marks, so long as the work on your show your work sheet is correct. a) Draw the direction of the electric field that will exist between the plates. b) Assuming the energy of the photons is greater than the work function, should a positive voltage or negative voltage be applied to the right hand plate in order to block current flow? c) If the energy of the photons is [Eph] eV and the work function of the material is [wf] eV, what magnitude of voltage must be applied to JUST block the current?  

On your show your work document do the following. Consider the below energy level diagram of a material. Energy level  n=1 is [e1] eV, n=2 is [e2] eV, n=3 is [e3] eV and n=4 is [e4] eV. Consider an electron which transitions from n=1 to n=3. a) Was this an emission or absorption event? Briefly Justify your answer. b) What is the wavelength of the absorbed/emitted photon in nanometers?
