Evaluate what is the material work function

Reference no: EM13657306

Red light of wavelength 665.9 nanometer produces photoelectrons from a certain material. Green light of wavelength 523.0 nanometer produces photoelectrons from the same material with 1.50 times the previous maximum kinetic energy. Evaluate what is the material work function? Planck's constant is 6.63 × 10-34 J • s and the speed of light is 3 × 108 m/s. Answer in units of eV.
