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 cm2. (a) 4.26x1014 photoelectron/s (b) 7.09x10-14 photoelectron/s (c) 7.09x104 photoelectron/s (d) 4.26x102 photoelectron/s A light of wavelength 352 nm with an intensity 2.00 W/m2 is directed at a metallic surface.
