A photon with wavelength (2) of 530 nanometers strikes a metal plate. The metal plate has a Work Function (W) of 1.95 eV. The photon “kicks" off an electron, giving the electron a certain amount of Kinetic Energy... (Einstein's Photo-Electric Effect). The electron then gains energy, and accelerates towards the positive (+) parallel plate. Question A: Calculate the initial velocity (Vi) the electron has just after it is kicked off the negative (-) plate by the Photon. Question B: Calculate the final velocity (Vr) the electron just before it strikes the positive (+) plate.

(5) A certain type of Vacuum Tube is made with two parallel plates which function like a capacitor. A voltage potential of 80 Volts is applied across the two parallel plates. The Vacuum Tube is built with glass so photons can strike the bottom plate which is negatively charged. See Diagram below. A photon with wavelength (2) of 530 nanometers strikes a metal plate. The metal plate has a Work Function (W) of 1.95 eV. The photon “kicks" off an electron, giving the electron a certain amount of Kinetic Energy... (Einstein's Photo-Electric Effect).
