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.

h = 1.9 m d = 3.5 m = 41 degrees

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? please write in in m.
