Abstract: In the lab, the photoelectric effect and its relation to Planck’s constant was studied. In each part of the lab, a multimeter was set up to record the stopping potential of different wavelengths of light. In the first part of the lab, a stopwatch was also used to record the charge time of the apparatus. For part II, it was found that stopping potential did not depend on intensity of light, supporting the quantum model of light. In part III of the lab, Planck’s constant was found to be 6.27x10 -34 ± 0.36 Js, which agrees to within uncertainties with the accepted value of 6.626x10 -34 Js. Data Analysis and Results: Part II: Intensity Dependence Table I. Stopping potential and charge time of violet and green light at 4 different %T. Stopping Potential (V)
