  1. The equation for the Kinetic Energy, [tex]KE_e[/tex], of the photo-emitted electrons is given as follows;

    [tex]KE_e = h\cdot f- BE[/tex]

    Please find attached the required plot of the kinetic energy versus the frequency

    Explanation:

    The equation for the Kinetic Energy, [tex]KE_e[/tex], of the photo-emitted electrons is given as follows;

    [tex]KE_e = h\cdot f- BE[/tex]

    Where:

    h = Planck's constant = 6.63×10⁻³⁴ J·s

    f = Frequency

    BE = Binding Energy = 2.71 eV  for Calcium metal

    f₀ = Threshold frequency for the material

    The ionization energy is the energy required to free an electron from an isolated atom
