A student performed a photoelectric effect experiment in which he exposed an unidentified metal to various frequencies of incident electromagnetic radiation and measure the stopping voltage of the emitted photoelectrons. He calculated the maximum kinetic energy of the emitted photoelectrons. His results are given in the table below. Frequency of incident electromagnetic 1.3 1.4 1.5 1.6 1.7 1.8 Radiation (1015 Hz) Maximum kinetic energy of emitted Photoelectrons (10-19 J) 1.0 1.8 2.4 3.1 3.8 4.4. The teacher provided the student with the following table of work functions for selected metals. Metal Work Function (eV) Na 2.28 Co 3.90 Pb 4.14 Ag 4.73 Pt 6.35 You must completely analyze the data and identify the metal. In your response, Identify the region of the electromagnetic spectrum to which the incident frequency radiation belongs. (1 mark) Provide a graph of the results on the next page. (3 marks) Determine the value, with units, of the slope. Identify the significance of the slope. (2 marks) (v - axis) Determine the values, with units, of the x-intercept and the y-intercept. Identify the significance of each of the intercepts. Use your results to identify the metal. Justify your answer. (3 marks) (Title) (x-axis) 5
