Homework Equations
I haven't been able to attempt the problem because the book we use for optics has nothing covering this information. If you don't mind giving me an equation to start with or some guidance on how to start the problem I \'d greatly appreciate it. Our teacher was out of town so we were left to try and figure this out on by ourselves... :/ Thanks for anything you can help me with!
