ii) A physics instructor conducts a photoelectric experiment with sodium as a target material. The instructor shines a decreasing range of wavelengths on the sodium sample and measures the kinetic energy of the ejected electrons. inn) imam dummy; Ian- \"- \" \" \" _ a) Complete the table by calculating the frequency for each corresponding wavelength. b) Plot all possible values on kinetic energy versus frequency graph. G) Determine the value of the xintercept. Explain its meaning. d) Use the data to calculate the slope( with units) of the graph. e) Explain why some wavelengths do not produce any ejected electrons
