White light (ranging in wavelengths from 380 to 750 nm) is incident on a metal with work function Wo = 2.46 eV.
(a) What is the maximum kinetic energy of the electrons emitted from the surface?
KEmax = eV
E = hf = hc/lamda.
E = (6.626*10^-34)(3*10^8) / (750*10^-9) = 2.6504E-19
I know to get KEmax i need to do 2.35- something = 0
Thanks
