Slowly move the intensity slider from 0% to 100% and observe the photoelectric effect. The electrons emitted from the metal are called “photoelectrons.” They have the same mass and charge as any other electron.
The Photoelectric Effect (at home) Purpose:To investigate the nature of the photoelectric effect and determine the work function of an unknown metal Apparatus: Computer, Simulation: “Photoelectric Effect” (available at https://phet.colorado.edu/en/simulation/photoelectric), spreadsheet software (Microsoft Excel or equivalent) Discussion When light shines on a polished, unoxidized metal surface, electrons can be ejected from the metal. This is […]
