Answer

This severed look is because the angle of refraction is different for the air-glass interface than for the water-glass interface. The top portion refracts from air to glass, and the bottom portion refracts from water to glass. This is different from what's in Fig. 22.13b. In that figure, we see the top portion in air directly and the bottom portion in water through refraction from water to air. The angle of refraction made the pencil appear to be bent.
