Spot of light hit the bottom of the pool

Reference no: EM13660165

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