Question 9 10 points Would the photocathode used in this experiment emit electrons in the dark, as a consequence of being at room temperature? @ Yes, but not many because the average thermal energy of the electrons at room temperature is less than the work function. There will be a few electrons in the Boltzmann distribution of their energies with enough energy to get out. 0 No, it is a simple cutoff of energy and this is high enough that noe of the thermal electrons in the solid can escape. 0 Yes, it is a simple cutoff of energy and this is low enough that all the thermal electrons in the solid can escape. O No. Since the average thermal energy of the electrons in the cathode at room temperature is less than the mean for a Boltzmann distribution, there are no electrons with enough energy to get out
