Work function values are often given in electron volts (1 eV = 1.602 * 10-19 J) .You create an oxide material that has a work function of 6.10 eV.How many electrons would be emitted from the material per second when it is irradiated by the 172 nm light of a 55.0 W xenon excimer lamp, and what is their kinetic energy? Assume all of the incident photons cause electron emission.
A) none; 172 nm is not energetic enough
B) 8.70 * 1017 electrons; 8.70 * 10-19 J
C) 4.78 *1019 electrons; 1.73 -10-19 J
D) 5.5 *1017 electrons; 5.40 *10-17 J
E) 1.86*1016 electrons; 5.37 *10-17 J
