1. The problem statement, all variables and given/known data What is the frequency of a photon of energy 58eV? 2. Relevant equations E=hF where H is Planck's constant, 6.63x10^-34 3. The attempt at a solution 58/ (6.63x10^-34) = 8.75e34 that is not correct. Do i have the energy eV into a certain unit?
