Unformatted text preview: of cesium is 1.9 eV. Calculate the maximum wavelength of light for the photoelectric emission of electrons from gold and cesium. The maximum wavelength occurs for the minimum energy for emission, which is just the work function. Now, Now, this leads to a maximum wavelength of 0.254 microns for gold and 0.654 microns for cesium. 2.9 An electron and a photon have t...
