Question

8. (1 Point) Suppose you set up the experiment so that the plate is ejecting electrons. Predict which of the following changes to the experiment could increase the maximum initial kinetic energy of the ejected electrons. (Select al that apply) Then test your prediction. A. Increasing the intensity of the light beanm B. Decreasing the intensity of the light beam C. Increasing the wavelength of light D. Decreasing the wavelength of light E. Incre F. Decreasing the frequency of light G. Increasing the voltage of the battery H. Decreasing the voltage of the battery I. Replacing the target with a material that has a larger work function J. Replacing the target with a material that has a smaller work function asing the frequency of light 9.(1 Point) Suppose now you set up the experiment so that the plate is NOT ejecting electrons. Predict which of the following changes to the experiment could make the plate start ejecting electrons. (Select all that apply-Options are the same as in the previous problem) Then test your prediction. 10.(1 Point) What causes the electrons to be ejected from the left plate in this simulation? A. The force exerted on the electrons by the battery B. The beam of light shining on the plate C. Both A and B D. Neither A nor B.
