1. The problem statement, all variables and given/known data http://img215.imageshack.us/img215/8457/physicsol4.jpg [Broken] 2. Relevant equations n1sin01=n2sin02 1/f = (n-1)(1/r1-1/r2) 3. The attempt at a solution I'm really jus confused with this problem I don't really see where to start. I'm assuming the fish bowl is a converging lens? I still don't know where to go from there though.
