Question

-Compare two different targets in the PhET simulation. You may select one of the known targets (sodium, zinc, copper, platinum, and calcium), and use the unknown target. Collect electron energy versus light frequency data for each of the three targets. Take screenshots of the graphs for each target

-Compare and contrast the three targets. Summarize your findings in a table. Discuss your findings in a paragraph. Your discussion should include:

1. Comparison of the slopes, x-intercepts, and y-intercepts for each graph.

2. Comparison of the work functions and threshold frequencies for each graph.

3. Description the effect of light intensity on electron energy.
