Unformatted text preview: energy = Planck's constant x frequency o E = hn energy quantized, can only increase in steps (though steps are extremely small) photoelectric effect- photons striking metals cause electrons to be emitted o photon- energy packet, transfers energy to electrons o energy of photon = E = hn 6.02 x 1023 photons per mol Find energy of 1 photon light w/ wavelength 589 nm c = nl 3.00 x 108 m/s = n(589 nm) n = (3.00 x 108 m/s) / (5.89 x 10-7 m) = 5.09 x 1014 s-1 E = hn E = (6.63 x 10-34 J-s)(5.09 x 1014 s-1) = 3.37 x 10-19 J/photon...
