Dr. Evil found Austin Powers hiding in an aquarium filled with water (n=1.33). The window glass (n=1.5) is 3 cm thick and Powers is 5m below and 10m away from the window. Sketch the scene. If Dr. Evil uses a laser to shoot his targets, at what angle should he fire to hit 007? How does this differ from the direction Powers appears to be? How deep would Powers have to dive (staying same distance from window) to avoid getting blasted?
