A device called a photocell detects light by letting it fall onto a metal and then measuring the current from the ejected electrons. You are designing a photocell to work with visible light and are considering the use of either molybdenum (work function = 4.2 eV) or sodium(work function = 2.4 eV). What is the lowest photon frequency that can...
