In searching the bottom of a pool at night, a watchman shines a narrow beam of light from his flash-light, 1.3m above the water level, onto the surface of the water at a point 2.7m from the edge of the pool (Fig.23-50). Where does the spot of light hit the bottom of the pool measured from the wall beneath his foot, if the pool is 2.1 m deep?
