A light of wavelength 352 nm with an intensity 2.00 W/m2 is directed at a metallic surface.
Only 0.60% of incident photons will produce photoelectrons. Calculate the number of
photoelectrons emitted per second if the metallic surface has area of 2.00 cm?
h (a) 4.26x10^4 photoelectron/s
(b) 7.09x105'4 photoelectron/s
(c) 7.09x104 photoelectron/s
(d) 4.26x102 photoelectron/s
