quantum 1: Problem 6 point) A calcium surface (work function o - 2.87 eV) is illuminated with 250 nm light from a 3 mW laser. How many photons per second are emitted by the laser? photons per second Only a small fraction of these photons can interact with electrons at the surface. Suppose this fractional efficiency is 1%. What is the current in the detector assuming all the emitted electrons are captured? nA Note that current is charge (in Coulombs) per second. The charge of one electron is 1.6 x 10-19 C
