Cesium metal is to be used as the photocathode material in a photoemissive electron tube because electrons are relatively easily removed from a cesium surface. The work function of a clean cesium surface is 1.9 eV. What is the longest wavelength of radiation which can result in photoemission? a. b. If blue radiation of wavelength 450 nm is incident onto the Cs photocathode, what will be the kinetic energy of the photoemitted electrons in eV? What should be the voltage...

Four questions. Please answer with all work shown so I can learn the methods. Thanks (1)Two 2 cm-diameter disks spaced 2.187 mm apart form a parallel-plate capacitor. The electric field between the disks is 464,475.983 V/m. An electron is launched from the negative plate. It strikes the positive plate at a speed of 29,140,951.095 m/s. What was the electron's speed as it left the negative plate? (2)Two equally charged, 3.549 g spheres are placed with 2.925 cm between their centers. When...
