A light soure, S, is located 2.0 m below the surface of aswimming pool and 1.5 m from one edge of the pool. The pool isfilled with water(n=1.33) to its top.

a. At what angle does the light reaching the edge of the pool leavethe water?

b. Does this cause the pool to appear to be deeper or less deepthan it actually is?

A person is standing at the edge of a pool 2.1 m deep. The pool is filled with water of index of refraction n = 1.33. Light traveling from an object at the bottom of the pool emerges from the water and travels to the person's eye. The light traveling in the air to the person's eye makes a ϕ = 45° angle with the normal to the surface of the water. The person's eyes are 2.1 m above the ground. (y₁ = y₂ = 2.1 m)

Find the distance x of the object from the edge of the pool.

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 θ = 36 degrees with respect to the water's surface. The pool is d = 2.75 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?
