See below.

Work Step by Step

The surface of the choppy water acts as a diffuse reflector. As Figure 28.10 illustrates, diffuse/specular reflection from a rough surface bounces every which way. At practically every location in the water between you and the sun/moon, there is some facet of the water surface that reflects the light to you. If the water were even choppier, the column of light would become wider. If the water surface were as smooth as a mirror, you would see an image of the round sun/moon on the surface of the water.
