The plot of kinetic energy of the ejected electron versus frequency, for three (not drawn to scale). unknown metals (X, Y, and Z) is shown 1 eV 1.6022 * 10- J Answer the following questions: Frequency (s-) Kinetic energy (J) The three possible values corresponding to work functions for the metals shown, are 4.96 eV, 3.10 eV, and 2.07 eV (in no order). Which one of the following metals (X, Y, or Z) will emit the slowest (lowest velocity) electron when excited with a photon of an ultrafast laser pulse (375 nm)? What is the velocity (ms-) of the ejected electron (3 significant figures)? Show your work and calculations. Assume the plot shown (for X, Y, Z) represents the ejection of easiest to remove electron in metals Ca/Ba/ Sr. Which of the plots (X, Y, or Z) corresponds to Ca? Explain your reasoning.
