Stranded on a desert island, tom Hanks is hungry.

Stranded on a desert island, tom Hanks is hungry. He sharpens a stick per the suggestion of his volleyball, and makes ready to hurl it at a fish, minding its own business in the gentle shallow waters inland from the breakwater around the island. If the image of the fish is 1 meter below the surface, how far down is the real fish? The indices of refraction for water and air are 1 and 1.33, respectively. Please note that the light coming from the fish begins underwater.
