It's very common to photograph either the moon or a lighthouse being reflected in fairly calm (but not completely flat) water. The usual depiction shows the bright reflection appearing as a wedge that grows wider as it approaches the viewer, with the wedge point either near the lighthouse or (in the case of the moon) near the horizon. Find such a photograph, describe the notable features of the reflection (such as the shape of the wedge), and explain them in terms of the physical models you've seen in this chapter
