A point source of light is submerged 2.1 m below the surface of a lake and emits rays in all directions. On the surface of the lake, directly above the source, the area illuminated is a circle. What is the maximum radius that this circle could have? Take the refraction index of water to be 1.333.

You are standing in a 1.5-m-deep swimming pool at night. The water is very still. You hold a laser pointer just above the water's surface and shine it nearly parallel to the surface, but tilted slightly down so that the beam enters the water 3.5mfrom you. How far from you does the beam strike the bottom of the pool? Index of refraction of the water is 1.33.
A flashlight is held at the edge of a swimming pool at a height h = 2.2 m
A flashlight is held at the edge of a swimming pool at a height h = 2.2 m such that its beam makes an angle of θ = 58 degrees with respect to the water's surface. The pool is d = 1.5 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 port on the bottom of the pool...
An expensive spotlight is located at the bottom of a gold-plated swimming pool of depth d = 1.00 m (see Figure). Determine the diameter of the circle from which light emerges from the tranquil surface of the pool.

A 200 cm long vertical pole extends from the bottom of a swimming pool to a point that is 64 cm above the water. Sunlight is incident at 55° with respect to the surface of the water. (a) Find the length of the shadow of the pole on the surface of the water. (b) Find the length of the shadow of the pole on the bottom of the pool. Use n = 1.33 for the index of refraction of water.
