a) On the desktop of the lab computer go to "Course Folders/230/Lab 4" and open the file "Photoelectric effect simulation.jar" Technical help for using the simulation on your personal device: The simulation will not work on iOS or Android. On macOS or Windows it requires Java (http://www.java.com/en/download/ ) to be installed. You can find the simulation here: https://phet.colorado.edu/en/simulation/photoelectric. b) Before interacting with the simulation you need to make sense of what you are looking at. Create your own diagram of what you see in the simulation. As you progress through this experiment annotate and label the diagram with additional information so that someone looking at it for the first time would easily understand what everything is and what its purpose is
