When a beam of 10.6 eV photons of intensity 2.0 W m^-2 falls on a platinum surface of area 1.0 * 10^-4 m^2 and work function 5.6 eV, 0.53 % of the incident photons eject photoelectrons. Find the number of photoelectrons emitted per second 0.53 % of the incident photons eject photoelectrons. Find the number [...]
