Cоnsider the phоtоelectric effect experiment below, where the plаte on the left is being stimulаted by photons, аnd 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?
