6. The index of refraction of air is 1.0 and that of water is 1.33. You stand at the shore of a lake, spear-fishing for a type of fish you know likes to feed on the bottom of the lake, 1 m deep. You can see such a fish by looking from above down into the water at an angle below the horizontal of 40°. At what angle below the horizontal should you aim the spear? A refraction diagram will...
