A flashlight is held at the edge of a swimming pool at a height h = 1.9 m such that its beam makes an angle of  = 41 degrees with respect to the water's surface. The pool is d = 3.5 m deep and the index of refraction for air and water are n₁ = 1 and n₂ = 1.33, respectively. 

What is the horizontal distance, D, from the edge of the pool to the point on the bottom of the pool where the light strikes?
