How are photoelectrons released? This photon is below the threshold frequency …but the electron does not have enough energy to escape. One photon interacts with one electron… Sunday, 28 April 2019 Leeds City College

How are photoelectrons released? This photon is at the threshold frequency …and the electron has just enough energy to escape… …but will get pulled back by electrostatic attraction. One photon interacts with one electron… Sunday, 28 April 2019 Leeds City College
