6. (8 points) The radiation emitted during transition B in problem 5 is now incident on a metal surface of work mction 2.46 eV and electrons are emitted. The electrons travel toward the negatively charged cathode and complete the circuit as shown below. A potential difference supplied by a power supply is increased, and when it reaches a certain value Vs, no electrons reach the cathode. Lvmablc Power Supply (a) Calculate the maximum kinetic energy of the electron ejected from the metal by the photon. Mass of the electron me = 9.11 x 10 '31 kg (b) Calculate the stopping potential VS. (c) Calculate the de Broglie wavelength of the ejected electron. (d) Which of transitions A and C in problem 6, when incident on the metal surface, will also result in electrons being ejected from the metal? A only C only Both A and C Neither A nor C Justify your
