In the figure, a laser positioned on a ship is used to communicate with a small two- man research submarine resting on the bottom of a lake. The laser is positioned 12 m above the surface of the water, and it strikes the water 20 m from the side of the ship. The water is 76 m deep and has an index of refraction of 1.333. If the laser reaches the submarine, how far horizontally is the submarine from the side of the ship? 12 m + 20 m → 76 m
