You set up a photoelectric experiment with an unknown metal to eject electrons. You use light of wavelength λ = 660 nm, which just BARELY ejects electrons from the metal. Planck s constant is either h = 6.63 x 10-34 J.s or h = 4.14 x 10-15 ev.s. a) What is the binding energy of the unknown metal in eV? eV b) You change the light source to one with a wavelength of λ = 300 nm. Using the binding energy you found in the previous step, find the maximum kinetic energy of an electron that is ejected from the metal in Joules. c) What is the stopping voltage for an electron with the kinetic energy you just found?
