Thank you for replying! So as the rays head toward the eye, does the incident ray hit the edge of the tank (air-water boundary?) and then refract in air before it hits the eye? Sorry, I'm still a bit lost. Wouldn't they all still hit the eye?

The 80-cm-tall, 65-cm-wide tank shown in the figure is completely filled with water. The tank has marks every 10 cm along one wall, and the 0 cm mark is barely submerged. As you stand beside the opposite wall, your eye is level with the top of the water.
