A photoelectric experiment indicates that violet light of wavelength 420 nm is the longest wavelength radiation that can cause photoemission of electrons from a particular multialkali photocathode surface. a. What is the work function in eV? b. If a UV radiation of wavelength 300 nm is incident upon the photocathode, what will be the maximum kinetic energy of the photoemitted electrons, in eV? c. Given that the UV light of wavelength 300 nm has an intensity of 20 mW/cm2, if the emitted electrons are collected by applying a positive bias to the opposite electrode, what will be the photoelectric current density in mA cm-2 ?
