Find the kinetic energy of the ejected electron

Reference no: EM13154473

In the photoelectric effect an electron is emitted from a metal as the result of absorption of a photon of light. Part of the energy of the photon is required to release the electron from the metal; this energy ? is called the work function or binding energy. The kinetic energy of the ejected electron is given by 1/2 mv2= h v -?. where m and v are the mass and velocity of the electron. For the 100 face of silver metal, the velocity of electrons emitted using 200-nm photons is 7.42 X 105ms -1. Calculate the work function of this face in eV
