Question 15 The equation to compute the kinetic energy of electrons produced by the photoelectric effect is, Ex- hu- where is the metal's work function typically given in eV and is the frequency of the impinging photons. For one electron the kinetic energy is 1 me where me is the the electron's mass. Find the kinetic energy of electrons ejected from sodium when its surface is irradiated by photons with frequency 1.706-10¹5 Hz. The work function of sodium is 2.36 eV. Mind carefully the energy units in the answer and in your equations. Ek Submit Question eV
