The University of Colorado at Boulder has a great website with hundreds of interactive simulations. We are going to use one on the Photoelectric Effect. Go to [|**http://phet.colorado.edu/**] and click on //PhET Simulations// // à //// Play With Sims //// à //// Quantum Phenomena //// à //// Photoelectric Effect //// à //
 * __ Part 2, PhET __**
 * It should open a page that looks like the picture to the right.
 * Take some time and familiarize yourself with the excellent simulation. You can change the photosensitive metal observed, the light intensity (brightness), voltage added, and the very important EM wavelength.
 * Click on the boxes to show the graphs of I v V, I v A, and E v A
 * Use the simulation to answer the following questions #1-9. Be sure to provide qualitative and/or quantitative evidence from the simulation to support your answers. Show work when you do calculations. Organize your information in data table(s) when appropriate.


 * Part 2 QUESTIONS: **



The "Show your Work" in all caps was supposed to clue you in... You must show work for all calculations, as always: equations used, numbers plugged in, etc.
