After a long day of driving you take a late-night swim in a
motel swimming pool. When you go to your room, you realize
that you have lost your room key in the pool. You borrow a
powerful flashlight and walk around the pool, shining the light
into it. The light shines on the key, which is lying on the
bottom of the pool, when the flashlight is held 1.2 m above
the water surface and is directed at the surface a horizontal
distance of 1.5m from the edge (Figure 1).
