Question
Problem 4 (2 ...us): When light with a wavelength of 400 nm strikes a certain metal surface, the maximum kinetic energy of the emitted photoelectrons is measured to be 1.10 eV. a. (ts) What is the work function of the metal? b.ts) If light of wavelength 300 nm strikes the same metal surface, what is the shortest possible deBroglie wavelength of the emitted photoelectrons? (The electron speed is much slower than the speed of light.)
