Suppose the fractional efficiency of a metal surface with work function 1.42 eV is 1.0 x 10 14: that is, on average one electron is ejected for every 104 photons that reach the surface. What would be the current of electrons ejected from such a surface ifit were illuminated with 509 nm light from a 2.01 mW laser and all the ejected electrons took part in the charge flow? Number 8.24E-22 Units
