Archer fish often prey for flies that hover above the water. The index of refraction of water is 1.33. Assume that the archer fish is 1cm under water and the fly is 1cm above the water surface and that the physical distance between the fish and fly is 15 cm.

A. Sketch the ray diagram taking into account Snell's law.

B. Assume that the fish located the fly at an angle of 45 degrees (with respect to the surface normal), at what angle does the light travel above the water surface?

C. Considering the critical angle of total internal refelction, what would be a "safe" horizontal seperation for the fly?
