Suppose the fractional efficiency of a metal surface with work function 1.40 ev is 1.0 × 10-18; that is, on average one electron is ejected for every 1018 photons that reach the surface. what would be the current of electrons ejected from such a surface if it were illuminated with 510 nm light from a 1.75 mw laser and all the ejected electrons took part in the charge flow?
