In a photoelectric effect experiment, photons whose energy is 4.73 × 10-19 J are absorbed by a metal, and the maximum kinetic energy of the resulting electrons is Ekinetic = 2.78 × 10-19 J. Calculate: (a) the binding energy of electrons in the metal. (b) the wavelength of the light. (c) the wavelength of the electrons.
