Ultraviolet photoelectron spectroscopy (UPS) is an important analytical tool used to characterize the composition of materials in academic, industrial and national laboratories. The technique relies on the photoelectric effect where-in electrons are emitted from a material when it absorbs ultraviolet photons. Make a plot of the kinetic energy of the photo-emitted electrons versus the frequency of the incident light as the frequency is varied across the transition where photon energy exceeds the ionization energy (IE) of a material being examined by UPS. Label you axes.

The equation for the Kinetic Energy, , of the photo-emitted electrons is given as follows;

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

Explanation:

The equation for the Kinetic Energy, , of the photo-emitted electrons is given as follows;

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
