(a) If you are looking down into the tank from above, what is the apparent depth of the fish?
(The index of refraction of water is 1.33).
(b) Draw a diagram showing the real and apparent depth of the fish in water tank. (refer to Fig. 7).
(c) Assume you try to catch the fish using a fishing net. Can you catch the fish if you quickly move
the fishing net to the position where you see the fish in the tank from above?
