1. The problem statement, all variables and given/known data A beam of ultraviolet light with wavelength of 200 nm is incident on a metal whose work function is 3.0 eV. Note that this metal is applied with +1.0 V with respect to the ground. Determine the largest kinetic energy of the photoelectrons generated in this process. 2. Relevant equations Kmax = hf - phi Kmax = q*|V| 3. The attempt at a solution I am not entirely sure what the statement about the +1.0 V implies and hence I simply used the formula Kmax = hf - phi . Substituting the appropriate values gives Kmax = 5.139*10^-19 J . Am I on the correct path ?
