Question 16 of 16 In Einstein's photoelectric experiment, the kinetic energy (K.E.) of an electron displaced from a metal by a photon was the difference between the energy of a photon and a threshold energy value for the metal. If you were to perform a similar experiment with lead, which has a threshold energy of 6.81 × 10 19 J, and ultraviolet light of wavelength 38.5 nm, what would be the speed (v) of the dislodged electron? (K.E. = 1/2mv². The mass of the electron = 9.109 × 10 1 kg.) m/s 4 x 100 +/- to search 2. 3.
