Suppose the fractional efficiency of a cesium surface (with work function 1.80eV) is 1.0 x 10^-16 that is, on average one electron is ejected for every 10¹⁶ photons that reach the surface. What would be the current of electrons ejected from such a surface if it were illuminated with 600 nm light from a 2.00mW laser and all the ejected electrons took part in the charge flow?
