  1. Photoelectric Effect

    Linked via "Einstein's photoelectric equation"

    where $h$ is Planck's constant.
    When these photons strike the surface, they interact with individual electrons. The interaction is treated as a one-to-one collision. The energy of an incident photon ($h\nu$) is used in two ways: first, to overcome the binding energy holding the electron within the material (the work function, $\Phi$), and second, to impart kinetic energy ($K_{\text{max}}$) to the ejected [electron](/entries/e…

  2. Photoelectric Effect

    Linked via "Einstein's equation"

    $$K{\text{max}} = e Vs$$
    Combining this with Einstein's equation yields the linear relationship used for experimental verification:
    $$e V_s = h\nu - \Phi$$
